We pulled head today on #4 ----why is #4 mentioned alot? and found piston ring section jammed in intake valve port----and piston edge undercut away down to next ring except in one spot at bottom----4.0 ran fine with slight bad idle---#4 had 25 # of compression---rest ok. 95,000 miles--It was trying to overheat on 90' when it was idling with air on--no coolant loss.
The worst thing i have learned from reading alot of posts--

1---new engine will likely suffer same fate if one thing is wrong on my cooling system--
2--a new block is big bucks--$5k+
3- used engines are a crapshoot
4--this truck would sell for $3500-5000 if it had no problems---
5---I hate to lose----this is my biggest problem----

Thanks-

Have given this some thought----and seen prices on ebay for this year and model and have decided to put back together ----ir ran fine----and sell as a running parts car to someone who needs a perfectly sound RR and is not put off by the engine work----
