93 Mack E7 350 water in oil
Hope someone can help me here. I have a 93 E7 350 8LL Superliner that I just recently noticed my coolant level way low and checked my oil and it's way up. So I guess a head gasket is my problem here. The truck idles a lot on jobsites and it does have 580K miles but engine was rebuilt at about 525k miles. I bought the truck with 552k, it does not smoke, starts right up in cold weather without plugging it, no power loss.
Do you think it's the head gaskets. A few years ago I had a friend with an older EM6 300hp and I think it was something to do with a oil cooler gasket, not sure, but it did the opposite it filled his radiator with oil.
Any help is greatly appreciated and if it leads to be the head gaskets is this a known problem with the earlier E-7's and how hard of a job with the jacobs on top:thanks:
I have a 1989 E6 350 12sp Superliner and I ran it for 8 straight years and now all it needs is a clutch(thank you my 6 month old driver, keep your foot off it and take off in first not fifth and it would have lasted longer)
