Double Check - Oil cooler teardown

smount101 · #1 (**permalink**) 03-24-2012, 08:02 AM

Alright, getting ready for the teardown. Just wanted to give you my list of parts to order and see if i'm leaving anything out. Attached a file with parts, #'s and prices from tousley ford. Any advice greatly appreciated. Thanks guys.. BTW tore out the turbo last week and rebuilt with kit from riffraff. Pain getting it out for the first time but replaced all the seals in it and cleaned up. Went back together great and no more smoke! Gained some confidence now ready for the big teardown.

Truck also has a slight stumble to it... contemplating replacing injectors while the valve covers are off.. good idea?

Looks good to me. I wouldn't replace the injectors unless you know you have a problem with them. A stumble could be caused by a problem in the valve train as well. If you have AutoEnginuity, I would run a power balance to see which cylinder has lower power and then inspect the valve train VERY carefully for that cylinder and if it isn't valve train related, replace that injector. It's the perfect time to do it since you already have everything else apart.

How many miles on the engine?

I'm assuming these are original injectors, so at 150k you can start to see some problems with them. AutoEnginuity is diagnostic software that you can load up on a laptop and test for these things.

The more i read on here. I guess i would consider it a surge not a stumble. Around 2K RPM the boost and rpm gauge surge up and down slightly only when engine is cold it seems.

Does it surge when the engine is up to temperature? Are you tuned? Does it surge when you run stock tuning?
