Also has fresh oil and just started it up after sitting for 6 years

How is the oil level, has it increased?  How is the water level -has it  decreased?  Even if it's cold, the oil shouldn't be milky

Oil is midway on dip stick still translucent not opaque.
Level has Not changed. Only ran it for 10 minutes to move it to garage Water was low but didn't check it before moving it.

It doesn’t take much moisture to show up on a cold engine, so it could have been residual moisture. Did you run and warm the car before the oil change? If not, it may just have been a fluke. I’d throw a pressure gauge on the cooling system and see if it holds pressure. You can rent/borrow those cheap at any auto parts store.

If it has anti freeze in it, I’d be more worried about that in the oil and bearing damage. That’s serious if it’s going to sit. An oil sample (try the local truck stop is the stores don’t have it) will tell that.

My family is from Wallace, 6 years can be a lot of temperature/humidity changes up there. How’d it look with the timing cover off?

No it was cold when oil was changed as I had replaced the timing set. I'm going to change it again this week. I was wondering if I could have caused the leak by changing the water pump.
By miker - 4 Years Ago
Seems to me (been a long time since I had mine apart) there’s a bolt or two on the pump thru the cover and a water passage. So you need sealant on the bolt. Going to have to wait till someone with a better memory chimes in. It would be a slow leak on a cold motor, short running time.

Thanks for the info. I stop in Mullan regularly on my way to ski Lookout pass

I can confirm I did not put Sealant on the 2 bolts that pass in to the water jacket.
I hope this is the issue as the alternate is head gasket issues.

My first thought was a leak at the timing cover as a result of changing out the timing set.  But then you mention that the engine has not run for six years which adds a lot of new possibilities.  The timing cover is still at the forefront of all of those but nothing else is ruled out at this point.

I will suggest draining the oil and while the drain plug is out, do a pressure test on the cooling system.  If you have a problem with either the block, heads, or timing cover, then it's possible to see some water/coolant coming from the open oil pan drain plug.  You may have to leave the pressure on the radiator for as long as thirty minutes before enough moisture has accumulated to make its way to the oil pan drain hole depending upon the severity of the leak.  Fifteen psi should prove to be adequate for this.  If you see a coolant drip from the open drain hole, then it’s just a matter of finding the source of the leak.

Did you use some sealant on the timing cover gasket?  Never had a problem with front cover bolts that go into the water jacket, never used a sealant either (although it's a good idea)
By TNieland - 4 Years Ago
Yes I used a gasket and Sealant
