Hey. I'm new to this forum. I been reading around the newbie forum for quite a while now.I currently own a 98 elipse gsx with about 90k miles on it. Everything is stock on this car. I only had this car for about 3 months and now I'm having problem with this car. The car was overheating about a month ago, but that was taken care of when I changed the thermostat. After the overheating, the car was haivng a major oil leak. For some reason the oil leak went away and now I'm starting to get coolant mixed into my engine oil when i checked my dipstick. I had a friend looked it over and he said that i have a blown head gasket. I was just wondering if this might be the problem and is there any problem that could go along with it. I was reading around forum, try the search bar , but i can't seem to find anything that is similar to mine. I'm sorry for the long essay i wrote there. Anyways, i would aprreciate is so much if you guys would help. THank YOU!
 
coolant in the oil is normally a head gasket. when you overheated, it did it in, but by changed to t-stat, it must have prolonged it

Coolant causes the lube oil to change chemically as indicated by the milky appearance of the oil. Coolant contaminated oil does not provide the high lubricity required between close tolerance parts, thus causing friction heat. The heat causes more oil deterioration. Sludge begins to form, interfering with:

1. Positive operation of lubrication system pressure regulator valves and the oil by-pass valve.
2. Oil filtration suffers as filter material becomes plugged. The filter may even experience such
high pressure differential that interior parts may collapse.

This contaminated lube oil does not properly lubricate bearings. The first effect is excessive wear to internal engine parts. The oil does not provide the film strength needed between the rod and main bearings and the crankcase journals. High temperature friction melts and welds the bearing surfaces to the journals.

I'm surprised nobody else has asked this, but how hot did it get? At the very least I'd take the head to a machine shop and have it straight-edged.

+1. Its doubtful that the HG is blown. Normally an overheat warps the head, which requires resurfacing and then the associated HG replacement. Get new head bolts also. The stock ones are torque-to-yield and should not be reused. I am sure people do, but I wouldn't. I do beat the sh_t out of my car though. :D
 
Alright, Thanks guys. The car hasn't been driven since i found out about the coolamt. I'm waiting to get it fix.
 
Sounds like the head gasket to me... Either way you are going to have to take the head off so when you do take the head to a shop and have it checked and machined. Don't just put a head gasket on it or you may regret it. While your in there you might has well change the timing belt as well as the water pump.
