Hi everyone!
So after 2 years of owning my Clark C500S60, I've finally gotten to the point where I am starting to use it quite often.
I checked the oil the other day and it's gray. So then I checked the coolant and it's low. :(
If I let the truck sit for a day and check the oil, then it looks ok. It's only after it has run for 15 minutes or so that the oil is gray.
I pulled the oil fill cap and looked inside with a flashlight and I can see rust on the rocker arms. So moisture of some sort is definitely ending up inside the crankcase.
When considering the low coolant, a leaking head gasket is the obvious suspect.
However, since I don't know these motors very well, is there another common problem that could manifest itself as a blown head gasket? Are these engines known to crack the head or anything like that? I found a head set on ebay for $125 so that's not bad.
I need the truck really bad right now even though I know I need to fix this soon. The engine is still running well with no knocking, etc.
Can I warm it up, change the oil and filter and run it with a loose radiator cap for a bit longer like this before I fix it?
Any other gotchas to be concerned about when attempting this job?
Oh! I almost forgot. This particular truck has been converted to CNG, if that matters.
Thanks,
Michael
