Ok, so I changed my oil, fixed the fuel leaks, put in a fresh battery and everything was ready to try cranking for the first time....so I did.

After about 10 seconds it coughed but didn't catch. Tried again, couch - no catch and I noticed no oil pressure and I heard a leak - something giving off pressure. Got out and checked for fuel leaks again and found about 1/2 quart of fresh oil running down the fuel lines on the firewall, driver's side!!!:mad:

It isn't the valve cover gasket and I don't think :confused: it could be the head gasket....Are there oil system lines on the driver's side of the motor? I need some help here... I checked EPC and Germanica and couldn't find anything.

It was late last night and I was really frustrated, so I sopped up the oil and called it a night. Any suggestions on what I should check? I really want to hear it run before I have to store it for the winter.

Just a quick guess, but could it be your oil pressure gauge line?

Thanks guys.....you're right. I confirmed it over lunch today (lucky I work close to home). The plastic line comes off the back of the head and runs into the firewall, looks like it just blew. I'll try to get a pick...

At least I wasn't cranking it dry - and I proved (the hard way) I was generating oil pressure! Thank God for small victories!

Thanks, Rowdie, for the EPC link. I hadn't thought to look in the instrumentation section for a reason for my oil leak!

You said Guys...

Don't misunderstand... My post was to tally up that I got another one right... to go along with the multitude I have gotten wrong. :)


Just a light-hearted, rhetorical, OT post to provoke a smile...

Meanwhile back at the ranch...........
You are going to have the remove the instrument cluster to replace it. I tried different tubing and clamping methods but finally gave in and bought the part from MB. There is a reason we give a warning about starting the car with the cluster removed on the early models. You end up with a lap full or floor full of oil.
