My "new" engine….
 

Hello all. Here is a motor I just picked up to replace the knocking one in my X. The guy said he drove the X into garage and knew the chains were bad, but it ran fine. Just unloaded it and need to figure out a way to de-sludge it. Any suggestions other than total disassembly??? Obviously I am replacing all the TC guides/chains/ gaskets, etc. This is the worse I have ever seen. This is why you change your oil on a regular basis, to avoid this. BTW-$200 for complete engine…..

Yikes.

Sorry I have nothing helpful to offer. Score on the price though.

Is that rust on the cams?

The only way id trust a motor, if the sludge is as bad as you say, is if it were hot tanked and reassembled.

I dont mean to rain on your parade but how do you know that this engine does not have a knock in it like your old engine? The condition of that engine reeks neglect. I sure hope you are lucky with this one. Did you get a chance to see that it runs okay and just verify its timing guides? How many miles are on this engine? $1200 more and you could of have had better piece of mind. Wow:yikes:

He obviously did not see it run. Did you see the rust on the cams?

Yeah true. Really risky. Even the dismantlers will take a running video of an engine before removing from a vehicle. This would have given someone a better piece of mind regarding the condition of the engine. I wouldn't spend a dime on this engine, he needs to get a better donor. Maybe even buy a running craigslist car with the M62 engine and then junk the vehicle.

Thanks for the feedback guys. I need to really consider what I have here. I don't' want to do it twice. The rust on the cams comes off with a finger rub. It happens pretty quick here this time of year. I will put it on the stand and really take a close look tomorrow and find out what is going on. The guy I bought it from seems very honest. Just a little one man shop. He had 2 X's and was trying to make one good one. He seems pretty honest. I am very skeptical and asked lot's of questions. I will pull a main and rod bearing off to check conditions there and that will tell me a lot as well.

Well alright then let the adventure and investigation begin.

Usually when dismantlers have a good running engine, it's sprayed with rust-inhibitor, put in an oil vapor bag and stored in a warehouse.

This thing look like it been left outside and open (valve covers, timing chain cover and intake removed), even the fuel rails and vacuum lines left unsealed/exposed to NE elements can cause issues.

This motor looks shady.

Since you will have it on a stand, why not just disassemble it and see what you brought. You're going to drop the pan any way and the only thing left are the heads. If it was me, I'll just tear it down completely and just rebuild it, but that's just me.
