kelleyperformance Posted February 22, 2009 Author Report Share Posted February 22, 2009 (edited) well, went to move the truck today and no more lifter knock.... but the truck was overheating at idle. put it on the lift, found oil and coolant all over the undercarriage. didnt have time to find the source, but its looking worse and worse shift points are 6400, 6200. no TM, and line pressures are at stock values if i recall correctly.

zippy Posted February 22, 2009 Report Share Posted February 22, 2009 I wonder if you blew a head gasket? Are your pistons domed or inverted dome? Quote Link to comment Share on other sites More sharing options...
kelleyperformance Posted February 22, 2009 Author Report Share Posted February 22, 2009 it runs fine tho, thats the strange thing... if its moving or reving theres no overheating and the dipstick is actually showing about 7.5 qts in there... but i do all the matenence too and i did not overfill it. AND with it having at least a qt underneath it, that doesnt make sense.... they are inverted dome Quote Link to comment Share on other sites More sharing options...
kelleyperformance Posted March 2, 2009 Author Report Share Posted March 2, 2009 ok so the oil all over the truck wasnt mine... and thinking back, a mustang blew up in front of me at the tree. i guess i ran thru his oil... coolant was coming from the water pump, just changed the gaskets no more leak. however, lifters are definately on the way out. so i just need to take the heads off and put the crane ones in.

zippy Posted March 2, 2009 Report Share Posted March 2, 2009 You can probably get the GMPP lifters for less than $100. Why not use them? Quote Link to comment Share on other sites More sharing options...
kelleyperformance Posted March 3, 2009 Author Report Share Posted March 3, 2009 thats what im using now. and they are great. but i have a set of 8500 rpm crane cam $400+ lifters just sitting around. figure id have to be retarded to mess those up Quote Link to comment Share on other sites More sharing options...
F1SSS Posted March 3, 2009 Report Share Posted March 3, 2009 (edited) awesome . Good luck with low 12s and 11s JKP. truck looks like a butterfly (beautifal), stings like a bee (1 fast BA).
