Subject: Re: Oil cooler for 4.5 engine
Hi bill,
simple answer is that your engine is a bit tired and clearences have opened up a bit.
However don't worry your engine can go on for years like this as long as you have as a rule of thumb 10psi per 1000 revs while under load, Idle can be at 0 or 1 and I have seen it on many occasions with old engines but also seen those same engines still running 5 years later with much use in between.
Try using Motul 20/60 performance oil, it will do the same as your oil cooler idea but with a lot more simplicity.

Happy motoring,
Doctor J ;o)
