Alright. I followed the advice you guys gave me and I got it back together to spec, and it starts and runs really nice. Oil will still spray out of the dipstick tube when running, but not to the same intensity as before. I do not see any exhaust vapor/smoke coming from the tube after...

I have a stupid question that I already know the answer to, but I’m going to ask it anyway. :D. Is there any use/benefit in using a little gasket sealer between the bore and lifter valley to prolong the gasket from leaking there?

Thanks for your input. I have checked all of this - the muffler was the first thing to come off and get looked at. Definitely not plugged. Pics attached of the parts. The head gasket has a couple small chips out of the edge in the area where they burn through, but this happened when I...

Here are some photos. The edges of the head gasket are pretty flaky - which I would expect for a 22 year old engine. The little specks chipped off beteeen the bore and lifter/pushrod valley while handling it after removal. I don’t see any evidence of combustion residue outside of the bore...

I don’t reuse head gaskets. Not even the ones from 20-30 years ago. I don’t trust gaskets that compress when torqued will ever seal the same as they did the very first time.

Thanks for your input, fellas. The engine in question here is a 17.5hp Intek - it doesn’t smoke nor does the oil level drop. When I removed the head and head gasket, I removed it as carefully as I could being careful of the thin bridge between the bore and lifter/pushrod valley, which came...

Yes, I know there should be a slight vacuum in the crankcase. The breather works one way as it should - flow direction is to the carburetor. I have to pull the whole engine apart to swap rings, so I’ll clean everything up inside the breather. I normally wouldn’t be so nutty about an engine...

I don‘t like throwing parts at something in hopes of it working, but I don’t think there is anything else that can be done. I’ll pull it all apart and replace the rings, clean the breather/filter assembly, and reassemble with all new gaskets. A youtuber that does a lot of small engine work...

The head is still off of it. as I said in the OP; The gasket that I removed had NOT failed. It did come apart when I pulled the head, and as such, will be replaced with a new one. I have read numerous threads about oil blowing from the dipstick tube. Bad head gasket, plugged crankcase...

This engine has recently started having a problem with blowing oil out of the dipstick tube if removed during operation. It didn’t do this last season. I verified the crankcase breather is open and not clogged, checked the head gasket (it was GOOD before removal), and checked the cylinder...
