I've never seen the temperature go high on this thing. the fan runs almost all the time even though the sensor is reading at the very bottom of it's range. ive taken the cylinder head off. (nothing definitive but maybe a little fuel on top of piston with oil in it.i don't think this has anything to do with my problem )head gasket is 3 layers deep and I noticed some grit that might have been in between layers but nothing to say the head gasket wasn't intact. black carbon build up on piston. I've looked all over the head for cracks from over heating. I'm about to look again for hairline cracks that are extremely difficult to see. my buddy helping me said to order rings in case they are letting oil pass thru he also said get a new head gasket.. I'm looking at water in oil first and I'm not ordering rings. I haven't checked the oil cooler to see if it's defective yet. I'm just hoping someone had a similar problem. my only problem so far has been having to change the spark plug every 100 miles with 93 octane run thru it.
