I can't believe this happened.....engine is already in the car

Tippy · 10:54 AM

I put a hose clamp around the tube so I could rotate it with channel locks but no dice working
the O ring back in. As a prior aircraft mechanic, I'm mad at myself for not catching before hand but I built the engine on a wooden table and was so focused on cam timing.

Love to hear your thoughts....argh

I think I would cut or bend the tube and take it out and replace it with one of the expandable type. I can't see how you could get that seal back behind the lip at this point.

Tippy,

You will get better response if people reading your post could understand your situation. I have read your post multiple times and still have no clear idea what you were talking about. A picture could deliver a better message for us to comprehend your message. Thanks.

Ouch, two choices, expandable tube or you have to tear it down and reinstall the cam carrier.

If it were me, I'd first try lightly deforming the lip on the tube, then lube the crap out of the O ring and see if I could turn the tube while encouraging the O ring to slide past the bent lip. (And then bend the lip back.) Low percentage move, possibly.

And if I weren't happy with the outcome, go with an expandable tube.

To make your problem more manageable, learn from this blunder. You could fix and overcome this set back. If I were in your shoes, I would consider using a P-201 (engine yoke). This will make the work more convenient. Without one, you are putting your self in a disadvantage. While some people could get away without using P-201, I will not recommend it. I am not a professional engine rebuilder but have done more than a dozen rebuild projects.

We all make mistakes. And learned from this one. Find a P-201 you could borrow or even buy one and sell it later. I have 5 engine yokes and 2 are being used, so there are 3 available for you to borrow.

BTW, is that JBWeld I see between the cylinder heads and cam tower? It also looks like you forgot to install the cooling tins between the cylinders(?). Keep us posted.

Looks like ThreeBond on the cam towers, but good catch on the cooling tin. If you didn't install those then I would definitely pull the cam towers and install those and fix the oil tube at the same time.

Pull the cam carriers back off and start again. You're only out threebond and an o-ring (and of course, the labor). I think the pic is higher up than the cooling fins. They might be installed. If not, you'll have to remove the drainback tubes to install them on the cylinders anyway.

Dpmulvan · 02-01-2022, 07:56 AM

I agree on removing the engine from the car and dismantling and fixing properly. Cutting the tube could get metal in your motor. If nothing is hooked up a motor drop is half hour.

Crush it in the middle, pull it out and use a collapsible one, unless you really NEED to have everything look the same. BTDT. The pic doesn't show the cylinders and the air deflector area.

Mark Henry · 02-01-2022, 08:18 AM

John's right, heads, no tin there. And threebond... that will be a (not) fun cleanup.
I doubt spinning will work, even if it did it would likely cut the Oring.
Collapsing the tube and and using an expanding tube is what I'd do.

Tippy · 08:55 PM

Holy crap, I thought this didn't post. Didn't check back. LOL.

All the tin is there.

Stownsen914, we must be related. I'm always thinking outside of the box!! LOL

Although a collapsible tube is on the way, I may try that. I've had success working O rings back in but these are gigantic and under a lot of compression

Tippy · 02-02-2022, 08:54 PM

Thanks every one of you for your input!!

Much appreciated.

Tippy · 02-03-2022, 11:00 AM

Yes, that is Threebond oozing out of the towers. Last time I rebuilt it, I had leakage there.

stanglife · 02-06-2022, 04:45 AM

I'm going to vote for both. Sounds like the engine JUST went in. I wouldnt want an odd return tube...but I'm OCD

HOWEVER. In your case, I'd probably do the collapsing tube for now and go ahead, make sure everything runs right. Then pull it back out and fix the tube along with anything else you might find.

The only thing worse than pulling the engine apart to replace the tube, is finding yet another thing that might make you pull it apart AGAIN later.

Tippy,

If you had used a P-201 in your rebuild, you would had discovered during assembly that the green o-ring was not installed correctly. If I were you, I would borrow or buy an engine holder (does not have to be a P-201). A generic engine yoke (HF type) would be sufficient for your need.

Replacing this o-ring on a work table is not an ideal way to do it. Be smart and be prudent in your ways of fixing this unfortunate blunder. We all mistakes and learned from it. Wish you luck.

I think it can be pressed in. A threaded rod with small sockets and nuts should work.

Tony, I had one for over a year but gave it back before reassembly.
