USN 71-75 USS Saginaw LST-1188

Wanted to let everyone know that the engine is back in the car and running great. The machinist told me the degreeing was slightly off but nothing that would cause what we were seeing. He said the real problem was that the lifters were not bleeding down and that maybe increasing the timing...

This may be off topic a little bit, if so I apologize. Can anyone tell me about those hoses running from the Cowl to the Air Filter?

Thanks all. I'll post when we get the engine back in. Happy New Year.

My machinist came out today and agreed that the #1 intake valve was not opening where it is suppose to. We pulled the motor and laid it in the back of his truck. He'll take it back to his shop and go through it thoroughly. He apologized and said he would make it right. When complete, he'll...

Thanks, that's great.

If I'm understanding correctly, I only need to go as far as the intake valve starting to open at TDC instead of 34 BTDC to know that something is not right. All the other readings simply confirm it.

Great info on post #207,208, and 209. I followed it, but for me I'll have to read read it another dozen times (and I will) before it starts to click (no pun intended).

Understand. Thanks. (see reply above)

Understand what you're saying. Thanks. Just going for "ball park" readings, trying not to disturb anything the machinist assembled. He's suppose to be coming out to take a look soon.

Thanks guys. Christmas and family are in full swing now. So like someone suggested, I'll probably set this aside for a day or two. Looks like there is good info that was left today for me to absorb (if I can sneak away every now and then) :-) Merry Christmas! Duff

I was able to follow the article. Thank you. My set up presents everything bass ackwards. If I convert, the intake has just closed at tdc, it started to open at 10 BBDC, and therefore has a duration of 190, all in very rough terms. Which is still totally wacky. Now with a better...

I'm having trouble grasping this. Gonna take some time I think. It's not a matter of accepting or not accepting what you guys are posting, I just want to to be able understand. Thanks.

So the valve that my dial indicator is pointing to is the exhaust valve right?

Thanks, I believe after I messed with it for a while, it ended up in the middle of the roller at about a 90 degree angle. I have to pull the intake to get to the lifters wouldn't I? I've done the piston stop probably 5 times now so I'm pretty confident that the balancer is correct.

Thanks for posting the my cams specs. Keith had also hooked me up with a link in an earlier post. I'm attaching a couple of pics of the test set up. I used a summit timing tape. It only covered 60 degrees in units, not in this picture but I ended up extending the summit tape with gray...

With a home made 360 degree tape going around the harmonic balance 360 degrees TDC to TDC. Set up a dial indicator on the rocker arm roller for each valve separately. Intake: At TDC compression stroke the intake is closed, stays closed a full revolution (360 crank degrees) then starts to...

Thanks man.

Just got off the phone with the machinist. He's going to come out and look at the motor, he hopes next week. So that's great news. Regarding the Mancini timing chain. He said with the intake valve at TDC (Maximum lift?) it was off spec by around 10 degrees (ref degree wheel). He said there...

I think I follow you. Make sure there is a constant 12v going to the MSD Box when the ignition is "on". Good info on the coil. Thanks.

Have checked for vacuum leaks by spraying around the manifold and carb. Will look at retainers. Thanks.

Thanks for your thoughts. I'm a lot smarter now, in a large part, due to the feedback I've received in this thread. After this experience I may be ready to try doing my internals next time. The other thing I've learned is maybe "pay in full" should be negotiated up front with final payment being...

Thanks. Interesting about the reluctor blade. Good luck with everything.

Welcome from Lusby, Md. Nice ride!

Copy that. Thanks.

Patience? In medical terms my condition is described as Cranium Anesthesia, or numbness of the brain. Thanks for commenting your post gave me a laugh when one was needed.

After thinking more about it, I'm just wondering are those cam specs in crank or cam degrees. If I understand correctly 78 cam degrees would equal 156 crank degrees. My 180 out was an eyeball reading on the crank which would make 156 in the margin of error for eyeballing I'd think.

I sent the machine shop the picture of the mancini timing chain set. I also tried unsuccessfully to call him last week. Here's his response: ====== Hey Dan. December 13 TH Verizon was supposed to set up high speed Internet in my business but instead they knocked out my phones for a...

Thanks, no I haven't removed the timing cover. Other than the valve covers, I'm trying not to go into the engine. If it ends up back in the machine shop I want to lessen the chance of any finger pointing i.e. the machinist saying "you had the timing cover off how do I know you didn't didn't...

Great info thanks, I can certainly see how it would be confusing. I'll find out if my machine shop did the same thing but instead of calling Mancini like you did they just ordered a chain they were familiar with.
