How to diagnose worn rod bearings
Hi all.
I need advice for how to tell if my rod bearings need to be replaced.
Background: my car is a 2.8L stroker with a big turbo and all the other normal addons. It also has a big front oil cooler and a baffle plate in the oil pan. The engine was built in 2002 and has been in a few cars since then. 3 years ago it went into my car and has been used for about 5 De's a year. I bought the car last fall.
I don't know when the last time the bearings were changed.
In normal street driving, oil pressure stays high. Because of the oil cooler, oil temp stays at about 120 c on the street.
I did a de last weekend. Car ran great, but I was to busy driving to look down at the oil pressure. On track the oil temps reached about 200 c.
Before everyone says the obvious, I know I should replace the bearings. Problem is I have 3 De's coming up, and I'm not sure I have the time to do the bearings before then.
I am hoping someone can give me pointers on how I can diagnose the condition of my bearings. For example: with oil temp at x, and rpm at y, oil pressure should be z. I realize that all of my mods make this a difficult question.
Thanks for the help
