Changed my oil today. Engine is a 2002 LM7. ~5k on a H/C package from Texas Speed (224/228 112 cam, ported oil pump, stage 2.5 heads, stock compression). Oil looks like glitter, there was nothing large enough to grab inside the filter. Car runs fine and has ~60psi cold idle and nearly pegs the gauge at WOT. No strange noises other than the sewing machine noise its had since the swap. Parts all have blue silicone on them, I don't use blue on anything so it much be factory sealant. Any ideas? Assuming I need a motor but hoping otherwise.

Compression was tested a few hundred miles ago. ~180 on 7 cylinders. #8 is buried and I cannot get the compression gauge in there. Engine runs fine and pulls hard. Went 12.83 @ 113 about 500 miles ago.














I'm going to post this in the engine section as well, but many people here have been inside their engines.

Good call guys. Exhaust seals are gone on #2 and #5. #6 intake seal is starting to go. I wonder if TSP will do anything for me or if I'm eating a repair on a $2000 H/C setup with low miles.

Looked it up. Only 5200 miles, but 2 years since purchase. I think I'm on my own.

I did the install, but they were assembled heads.

Did you check retainer to seal clearance? It appears that the retainer hit the seal and fractured it. If it happened to one it is most likely happening to others.

No. Heads came new and assembled and the cam is fairly mild. I'll be checking that before reassembly though.
