Slowly but surely. Building our 2yo a playhouse for her 3rd birthday and gotta start on a garden shed so this has taken a back seat unfortunately.

Lol. Nothing super exciting. But, she’ll be thrilled when it’s done. We’re telling her it’s a tool shed for the lawnmower and she can’t play in it. It’s For her birthday next month.

I wanna make sure this is right or wrong. I’m replacing the front crank seal and it looks like the outer lip of the seal doesn’t sit flush against the crank. Is this right? It doesn’t feel like it should be. It’s an elring seal.

Thats fine, and on older engines it is preferable for the lip seals to ride deeper or shallower than normal to avoid riding in the minute groove that is formed on the shaft surface

That outer lip doesn’t even touch the crank. The inner seal do for sure, just not the outer one. That’s okay?

The actual sealing lip is further back like so.

Trust your gut, if you feel funny about it, redo it with a new seal and also check to make sure the aluminum seal housing is sitting flush on the block. Kind of a dumb suggestion but its the only thing im coming up with off the top of my head that could physically affect the seal position

That picture helps. It’s weird to me that this one would have that gap around the outer lip but the others wouldn’t. That’s why it’s throwing me off.

theres like 100 types of shaft seals, this should not be weird to you.

This is the first time I’ve seen one that was “open” on the face like that. It’s the only seal on the m20 like that and I’ve never seen one on all of the Volvo’s I’ve owned.

[Jdesign]

It's pretty common. A lot of hondas and aftermarket seals are like that.

[gilber33]

Oh look. More pictures of an m20 on an engine stand.

Tonight I got the old engine out and transmission off and moved some more stuff over to the new engine. 

Also so finished the roof on the playhouse. Need to put in one more window and then finishing trimming it out. Then the next project is a garden shed off the back of the garage and the siding that is coming off of the garage will be going on here.

What was the benefit of the new engine? lower miles? 

and stop trying to beat my record for M20 extractions!!!!

Lol. This is the 3rd time. 

I’ve never done a full tear down and rebuild of an engine. Was getting a lot of drivetrain noise and needed to pull the engine to check the clutch. Figured it was a good time to do and drop it in. Fresh hone, new rings, new bearings, and a refreshed head. 

We’re having our 3rd child in November and I decided while I have the time I’ll get this one in and get the car as reliable as it can be. We’re also doing a home addition next year, so I will very limited access to the garage.

Also, thank you to whoever updated the thread title. Lol

Still have plans to make the core support removable?

Not with this round of things. Don’t want to spend too much time with extra stuff. More focused on getting the drivetrain solid and running again. Eventually, yes.  

Maybe.

Kid #3 really cut into the time and money I had available for meth, hopefully you can maintain a proper balance

I mean, it is what it is. My wife and I have talked about what we can do to maintain the balance. If that’s picking up some side “jobs” here and there at night, requesting grants from business owners (mostly gas stations), selling my unused semen and bone marrow. There’s lots options.
