Hello Everyone,

I am having compression issues, Ref "http://geometroforum.com/topic/4869589/2/#new" :(


Anyway I ordered new lifters and wanted to replace them after testing leak down, or just replace them even if i need a rebuilt head. My question however is, when buying new lifters and putting them in do I just drop them in and hope for the best? or soak them in oil?, does it really make that much difference? i want to try to do this the best way possible! let me know!

Personal opinion: I would allow them to soak overnight in oil prior to install. You could just drop them in and go but you would likely have some "tapping" as they fill with oil and it may be tougher to get the engine started while they are pumping up.

I had the same tapping sound after completing an engine swap. I flushed the engine a bit with some MMO and the cheapest 5W30 oil I could find and the engine runs very smoothly as of now. I am hearing arguements both for and against Sea Foam in the oil. I have personally used in to clean out my engines right before I change the oil with great results but understand it is a pretty aggressive cleaner and may clean too fast if the engine has been neglected and has a lot of crud. I guess chunks of stuff can clog passages or get somewhere where it doesn't belong, potentially damaging the engine. I guess MMO works well but isn't quite as aggressive.

I have some MMO in my engine right now to clean out any crap that might have been in there. My engine wasn't too nasty inside but hearing that lifter noise made me concerned, plus I will get better MPG and use less oil if the ring grooves are clean and unstuck. I am assuming that this lifter bled down over time as the engine wasn't running for several weeks, had oil removed from it, it was tilted at all sorts of odd angles during the rebuild, etc. I don't know what the controlling factor was but suspect it was a little of everything, along with some crud in the oil.
