It took me forever and I'm not done. Im going to pull the intake cams and re time one bank at a time.
There is just not enough visibility to zip through without losing a valve.

This is my eBay cam timing kit for returning after cams off and seals done.
I'm at 1 month and only have bank1 donehttps://uploads.tapatalk-cdn.com/201...ac61563079.jpg

Wow. I wouldn't say this is a particularly difficult job but it's unbelievably tedious and there's 32 frickin seals to do!

I'm about 10 hours in and have only completed passenger side.

Probably comes down to previous experience + work area + available tools? I rented the AGA tools for two weeks and didn't return them till the very end. If I compressed all the time down, it' probably took me a week overall (although my 13 year old daughter helped a lot, so that probably added quite a bit of time to give instructions, etc).

Two hours to remove both valve covers?

You are my hero. :bow:

I am really not looking forward to this job.

That's about the time it should take for someone experienced with the job according to AGA. 20hrs start to finish.

So you're on right on track. Be patient. Keep reminding yourself you're saving yourself about a $2,500 bill from an indie repair shop.

Halfway through second bank now. If I were doing this again on my own car I would seriously consider just doing the exhaust valves first and see if it still smokes. Just those could easily be done in 8 hours, the intakes really are that much more difficult.


**** EDIT ****

Scratch that idea. I measured one of the valve stems and then with a rod that exact diameter started checking how snuggly it felt in the old seals. Basically ALL of them were worn out. More later in this thread.

Interesting. Does anyone know if the problem-child is usually the exhaust side? Makes sense due to heat. Would hate to have to put it together and take it back apart.
