It looks like there are balancing pads on the connecting rods right? Don't you just take some material off that with a belt sander to balance the rod/piston assembly?

Good day all!

It has been some time again. I have not gotten a lot done due to parts and my new job. Four days a week at work has turned into six days a week. I'm still trying to figure that one out...

So, I have all the piston and rods in. I finished the heads and even put the VANOS on the cams noting the Pass head has the vacuum slot...

I also put the timing chains on so that I could hook up the oil pump and put the oil pans on. I took out the wheel stud in the bottom of the oil filter cap and put in the new plug I got... Mental note: if the new one gets buggered up, leave it alone!! It doesn't HAVE to come out to change the filter...

Flywheel, real main seal, and all bolts torqued... Flywheel bolts got locktite...

http://i1084.photobucket.com/albums/...psiiuqktsh.jpg

Okay, now the fun stuff! I got the new guide rails for the timing chains... It escaped me to get the bits that go with the new rails... Pay attention to the stuff under the new items, especially if the original old part is "ENDED"!! So, I didn't get the new bolts for the rails... Here is the difference and the reason for the new bolt...

http://i1084.photobucket.com/albums/...psoytgtyny.jpg

New bolt is larger and longer... I don't have the new bolt yet... I'll explain why a little later...

http://i1084.photobucket.com/albums/...psljndovkj.jpg

And the biggest improvement noticed with these... This is incredible!!

http://i1084.photobucket.com/albums/...psbn2dztxj.jpg

And the last one!!

http://i1084.photobucket.com/albums/...pscn83o2f3.jpg

This is the issue!! I can't get more done until I get the new bolts!! I would put the cylinder heads on, but this motor needs the lower chain cover on first...

http://i1084.photobucket.com/albums/...ps4nben5nf.jpg

Well, I wouldn't say "NEEDS" the lower chain cover on, but things are much easier if it is...

Okay, here is the issue with the bolts...

I looked up the part number on realoem... Just like I always do... Find the correct diagram... Find the part needed... Look at the number next to that part... Scroll down until you hit that number and go across the line for the desired part number... Ahem.............. That didn't work out well this time!! It appears that not all options are designated with that number you scroll down to... Numbers 8 and 11 in my case... 8 and 11 are for the ORIGINAL bolts to be used with the "ENDED" guide rails... The new bolts that should have the 8 and 11 are listed under the new rails, but have dashes... So, I ordered two of what I already have!!!!

This is the WRONG part number for the new rails!!!

http://i1084.photobucket.com/albums/...psbzoausmf.jpg

Once I get all this done, I will be making a complete and triple verified list of parts for this...

So, until I get the two bolts, I'm stuck here...

Cheers for now!!!

:thumbup:Awesome progress!

Please keep us updated!

Looks great!

Good day all!!

Well, I got the bolts the other day! And here's all I got done...

Here is the difference between the bolts... And the correct part number...

http://i1084.photobucket.com/albums/...psn49impem.jpg

These came in handy for this motor...

http://i1084.photobucket.com/albums/...psdxbzw3xs.jpg

The boring stuff!! Cover is on and all torqued...

http://i1084.photobucket.com/albums/...psxrop2wax.jpg

I put sealant despite the pan gasket having it included... Do your own thing here...

http://i1084.photobucket.com/albums/...psy5fdfz5i.jpg

http://i1084.photobucket.com/albums/...psx34er9wn.jpg

I have both heads completely assembled so I had to take this off to get the bolt in and locked down... You also have to assemble the socket and extension through the Valvetronic...

http://i1084.photobucket.com/albums/...pskr9dp9qv.jpg

Some of these have to be turned to get them all installed... I have all the cams so they aren't putting any real pressure on the valves... So, you need to rotate each cam, one at a time and lock it in at that time...

http://i1084.photobucket.com/albums/...pshahqgq6m.jpg

I set it up, but didn't tighten down the cam bolts yet...

http://i1084.photobucket.com/albums/...psxde7lyht.jpg

THIS IS MY METHOD!!! GO WITH WHAT YOU KNOW AND TRUST!! I put all this work in to get this right, so I'm going to make sure the valves are not going to hit prior to timing...

I am able to rotate the motor over without the cams moving... I located and locked in one cam at a time...

So, when you have everything set, the 5-8 cylinders should look like this when at TDC... TDC is always for cyl 1...

http://i1084.photobucket.com/albums/...psf2kr1mer.jpg

http://i1084.photobucket.com/albums/...psxdvwcm3h.jpg

Cylinders 1-4... I didn't get a good picture like I did with 5-8... I will before I progress any further...

http://i1084.photobucket.com/albums/...psxiz7qtxj.jpg

Tool locked in place for the crank...

http://i1084.photobucket.com/albums/...psklyyjdrs.jpg

When using the locking tools, make sure you hold it in place with the bolt... You need to remove the oil rail to use that bolt hole... The cam bolts get 60 ft/lbs... The tensioner tool didn't have any pressure value that I could find!! I just snugged it up...

http://i1084.photobucket.com/albums/...pshze3fumo.jpg

http://i1084.photobucket.com/albums/...psyn5uwrrr.jpg

All done for now...

http://i1084.photobucket.com/albums/...pswgwis5pj.jpg

http://i1084.photobucket.com/albums/...psezvzrs0t.jpg

Here is another bit I found that some may not be aware of... This bracket has the same locking supports as the crank caps...

This is not in place yet... Other bolts are tightened up... I snugged these up as well... Think it calls for 20 ft/lbs...

http://i1084.photobucket.com/albums/...psvvkjya5d.jpg

8mm allen tightens it down...

http://i1084.photobucket.com/albums/...psfp8i6bum.jpg

Then the locking bolt that goes through it... You can get the cover bolt on with this in place... You can NOT get the guide bolt on with this in place... Ask me how I know... Ahem!!!

After you get this far, it is recommended that you rotate it a couple times and reinstall the tools to verify timing is still correct... I didn't get that picture...

Cheers for now all!!! Stay tuned for the install... And the first start-up!! Unless it fails, then I will mysteriously have won the lotto and move to the Caribbean!!!

Cheers all!!!

Good day all!!

Well, it has been a fun time these past few days!! Here is another picture of the cam positions at TDC...

Oh, don’t forget to clean this bracket!! It tells you a secret!!

http://i1084.photobucket.com/albums/...psejbwfw7l.jpg

I got all the brackets on the front... And the VANOS solenoids installed... Make sure they go all the way to the block!!

http://i1084.photobucket.com/albums/...psxompbbm7.jpg

For the valve covers... Get these!!!Mine are on the way...I would have them today, but I somehow missed ordering them this last go around...They should be here tomorrow...

http://i1084.photobucket.com/albums/...ps419vktql.jpg

Okay, that brings me up to today (9 June 2016)...... For the past few days I have been thinking about the union between the inner metal tube and the timing chain cover...I didn’t get the new tube...I just couldn’t justify the 63 bucks for a gasket...So, I made the seal out of some O-rings...However, in my mind when I set the initial position, I pictured a thin “oil pan” type gasket...Not the 1.5mm think gasket...I didn’t put two and two together until after I had it all together...So, I pulled it apart today to make sure this was not going to be the “common” failure point in this motor...I was right to do so too...I found the O-ring barely touching the timing cover...

http://i1084.photobucket.com/albums/...pshhgn129k.jpg

However, I also discovered that the gasket sealer got pushed through the gap between the tube and the gap...

http://i1084.photobucket.com/albums/...psnn106sms.jpg

I pulled this cover to access the pipe... If you reuse your old cover with just sealer holding it in place, be ready for some slow going getting it off...I pried up on the tube opening until I noticed the whole plate flexing!!I thought I was going to break the casting right where it dips down into the block...BUT, I am sure it won’t leak when I put it back!! So, I couldn’t get the tube free at the end... But, with no cover, I could wrap my hands around it here and spin it...I pulled the tube all the way out and started over...

I initially had two O-rings that were the same size... They fit between the pipe and the block...I used one of those and the old O-ring from the other end of the pipe...It was just about 4mm thick and gave me the perfect amount of room between the block and cover...

http://i1084.photobucket.com/albums/...psctj8qysp.jpg

With the cover off, my fingers kept hitting this gasket sealer... Grrrr!!The O-ring is just barely touching the cover here...And it has room to get pushed into the space where the second O-ring use to be...

http://i1084.photobucket.com/albums/...ps7zcstcrr.jpg

And the inside of the pipe... I feel confident this will provide way more seal than should be required...And dare I say, WAY better than the original method, even if it isn’t as pretty...

http://i1084.photobucket.com/albums/...pszvmta9iw.jpg

Ahhhhh, now the part that bothered me the whole time about this “rework”!! Pulling the cover off without touching the heads or timing...Oddly, it wasn’t that hard pulling it apart...Drop the bottom and top oil pan...I just loosened the top pan...

http://i1084.photobucket.com/albums/...ps4g4wskwa.jpg

http://i1084.photobucket.com/albums/...pspckipgqg.jpg

http://i1084.photobucket.com/albums/...pstkzld0xa.jpg

Slowly work the cover off evenly!!

Getting it back on is a bit more...... Annoying...Ya gotta make sure you get the thin layers of the gaskets in place before you get crazy about pushing the cover back in place...It is a tight fit under the head gaskets!!And the front of the oil pan gasket will catch on the cover when it is almost in place...

http://i1084.photobucket.com/albums/...psvmoj5pbb.jpg

http://i1084.photobucket.com/albums/...pshneypwqu.jpg

New pipe!! Get it...It’s only about $20...

http://i1084.photobucket.com/albums/...psgtgxour6.jpg

FYI... They put the pin and the crank key lined up with this rib on the cover when you are at TDC...

http://i1084.photobucket.com/albums/...ps7cwcraaw.jpg

That is about it for now... Almost time to get installed...I’m going a little slow now so I don’t rush to install it and forget something in the process...Think I may put the covers on now so I don’t have to deal with them later...

http://i1084.photobucket.com/albums/...pszuwwnvkf.jpg

Cheers for now all!!

Did you change the internal seal of that vacuum pump? It tends to leak.

Good day!

I have not yet... I actually didn't know there was another gasket in there... Good to know!! I might go do that right now... I'm curious!!

Thanks for tuning in and sharing the info!!

Cheers!!
