Full Version: Urgent question - stripped oil pickup bolt

Dropped the motor on my street car for hell hole rust repairs. As long as I had the motor out, thought I'd fix a few oil leaks, which I thought were mostly old push rod tube seals having given out. Just discovered the bolt that holds the oil pickup tube is stripped. That will definitely be a leaker too. The real fix for this is to of course split the case and heli-coil the stripped threads. Really didn't want to go there. Does anyone have any suggestions for a fix for this that DOESN'T include splitting the case?

Any suggestions would be appreciated.

Thanks,

Andrew B.

Sounds like you have the dreaded “Type 4 Syndrome.” It’s likely that the middle cam bearing boss is cracking. The case needs to be welded to fix it, and possibly line bored. I had the same thing happen. It’s cheaper just to source another engine and use it as is or rebuild it to your liking and install it. Your current engine is probably just parts now.

1st up try putting a new bolt in. 2nd shot is new bolt with split washer.

Just to be clear. Is this threads on the stud that holds the sump plate cover on? I would consider using red locktite, but you may not be able to get enough torque on it. What about using the next size down metric or standard die and make some new threads?

Unless it has "syndrome" you can use a longer bolt to cheat a little bit, and get some new threads. The issue with this is, pieces of the old threads that are damaged can end up in the oil sump.

If it has syndrome, tear it down.
