Do any of you know the oil system on the 401 engine? I pulled the valve cover the other day and noticed that oil was pouring out of the cyl 5 lifter and the associated head bolt at a very high rate. The head bolt washer was malformed and I sealed it but the lifter continued to pour out oil, much higher volume than any of the others. I am just wondering if each cylinder has a separate oil path and if a lot of oil coming out the lifter means inadequate oil at the camshaft for that cylinder.

If there is oil pouring out past a lifter, then you have a cracked block. The main oil gallery intersects all of the lifter bores.
If you have metal in the oil on top of all this, then it sounds like it's time to put the old girl out to pasture. Not many 8000s out there are worthy of a several thousand dollar engine overhaul, if you could even do it.

Thanks Bern. I can't do an overhaul for sure. I hope to have the equip and knowledge one day but I'm not there yet. Can you give me some idea of why oil gushing out at #5 would indicate a crack? Is that because pressure from the cylinder is driving the oil out that lifter? Are there other possibilities that I might troubleshoot? Unfortunately, scraping this tractor has some some serious implications for me so I can't take that decision lightly. My mech can't even touch it until next week which is almost too late. Thanks!
