The problem still persists but no issues with any cylinders misfiring or running issues so I still don't think it is getting into the cylinders. Still want to cover other possibilities before taking the heads off. Can water get into the oil without getting into the cylinders due to a bad head gasket? Is there any other water to oil interchange point I should be looking at? There is no oil cooler built into the rad just a tranny cooler, but is there an oil cooler built into the block on an SBC?

Hi Shaggy, 1. Yes. 2. Not positive, but, I don't think so. 3. No. Unfortunately, If there is water mixing with the oil, or oil mixing with the coolant... That motor is so clean, I wouldn't want to have to go that deep either Mate, but. I still enjoy needling Leonard about my "Rebuilt" 327 Plus. William of Ockham came up with that pesky theory called Occam's razor.

If anyone else has any other suggestions for things to check before I get stuck into that let me know.

I'll be doing this myself soon as I just discovered oil in my coolant after the van started steaming off on cold starts. Not the thing I wanted to find, that's for sure.
Hope the job goes easy for you, Shaggy. | | | Re: blown head gasket :eek: | Joined: Apr 2004 Posts: 2,026 Likes: 50 veteran | OP veteran Joined: Apr 2004 Posts: 2,026 Likes: 50 | I'm just putting an order together for rock auto to buy all the necessary parts.
Gaskets for the distributor / inlet manifold / exhaust headers / Cylinder Heads and a new set of cylinder head bolts. I'll get coolant, engine oil flush and fresh oil locally.
Anything I'm missing from that list?
Good luck with yours too Rusty, lets keep posting on this thread and hopefully it'll prove helpful to each other or fellow vanners.

I'll try to add if I can. I'm not quite sure yet how, if, and when I'm going to do mine. I'm still a little stunned at the bad timing (I've already got too many stalled projects). | | | Re: blown head gasket :eek: | Joined: Jun 2010 Posts: 18,278 Likes: 552 | Joined: Jun 2010 Posts: 18,278 Likes: 552 | Sell the rest ... fix the best !

Valve cover gaskets. Plus have a quality machine shop that you trust check the heads if there is any question on condition. Save you a ton of heartache, time, and money. Good Wrenching! | | |
