New to me TC29D cranks & won’t start

[D&D]

Facts are facts.

I’ve only read your opinions.

 

[CalienteJohn]

I'm with you here. 3 things don't fail all at the same time like this and re ringing a engine isnt a quick and easy job. I would be checking alot of other things before I just go ripping and tearing at the engine.

Theres plenty of other cheap/free checks and adjustments you can do before you just start throwing parts at something.

This has always been my frame of mind with repair work, try the cheap/free things all first.

Any more of those that I can still do moving forward

Only part I’ve bought so far is an oil and fuel filter. Plus compression tester replacement I’m gonna return for other tools haha

I’ve only read your opinions.

It is a fact that the explosion cannot push the injectors open, therefore the compression can’t either. How would the engine run with compression pushing air up the injection lines? This is not an opinion.

 

[CalienteJohn]

That’s almost funny. If the injectors leaked back how would they handle the explosion?
The surface area of the nozzle is so small it can’t push back. The blow by tells the story. So much guessing on here the guy is just chasing his tail until the main thing is corrected.

So what story does blow by tell

Pull head and check gasket or ? Yes I’m chasing my tail but I’m learning a lot along the way ! Or at least feels that way

Come on guys be nice
All good

I think he meant leak around the injectors not back through them if I understood correct the way he phrased it.

It tells you the rings are letting the compression to get by and show up in the crankcase as it is showing.

If it leaked around them you would see or hear or feel that.

I am looking at the landscape around your pictures trying to figure out what part of central California. I guess I am central foothills.

Other than that there is no such thing as an explosion in a gas or diesel engine, facts exist per case and can belie what we've learned/experienced in the past. The viewpoint depends on the relative pressure resulting from one of three events. These injectors aren't right anyway, so ... ?

Only part I’ve bought so far is an oil and fuel filter.

Wow, am I glad to hear that. We keep talking serious disassembly and inspection that I'd also hope to avoid. I'd look for an injector service and have them cleaned and adjusted before I took more apart. Spray pattern in #1 looks close, #2 ghastly, and #3 non-existent. I wouldn't be surprised if this one wouldn't start and run after such service. We can search for other demons from there but IMO this is big and at this point comes first.

I'd also keep soaking the rings, adding occasional (weekly) 1/2 ozs of acetone to the 1/2 oz or so of ATF in each cylinder. Apologies for my Scottish approach, but too often compression tests have mislead on engines that sat for too long and with rings that would eventually become unstuck(?), and/or engines that after inspection started and ran well with good mpg or GPH despite initial scary compression tests. (Honda, H-D, OMC, Chev/GM, Buick, Suzuki ...)

Just my opinion. Here today, gone tomorrow.

I agree plus they were super tight
Just reading his post and trying to understand what he was trying to explain.

I’m just chasing my tail around trying to follow everyone here haha

Near lake Isabella
Havilah CA

Central foothills is exactly how I’d describe it here

High enough altitude we get snow but enjoyable amounts of it is all. Horse property couple of cows 40 acres in the family here .

 

[CalienteJohn]

Repeat pop test after tightening with wrench. Just testing for pop not spray patterns, gonna get rebuild all three.

I think you are doing an excellent job and are on the right track. Did you do this to rule out the pump?

Swap the one that’s NOT PUMPING to a different line..
THATS to rule out a bad cyl in the pump..

After doing that I would move forward with having the injectors rebuilt. It would be nice to hear that thing run once before going after the rings. There may be other issues you are not aware of yet that tells you it is not worth the effort.

Yes trying to test all necessary components before moving forward based on solid advise. Agreed it would be great to hear it run but even with good injectors rebuilt my compression isn’t high enough it sounds like to make it run..

I’m in the process now of getting injectors rebuilt rather then buying cheap online crap injectors.

I will begin adding atf 1/2 oz or so per cylinder every few days?

What about the acetone recommendation, couldn’t hurt, right?

My Irish friend tells me that copper wire came about when two Scots were wrestling over a penny. I'm not saying it's true, mind you, I don't wanna make any enemies.

It doesn’t hurt at all. With the injectors firing and a good hot battery you have a chance it will fire up. If it was a gear transmission and you have a way of pulling it with a good helper, it most likely would fire. If you do get it running, check everything out closely so you know where you stand. Keep a close eye on engine temperature and do not rely totally on gauges. Have a temp gun handy and listen to that engine. Don’t worry too much about excessive smoke. It will smoke like a tar kiln. This because of all the fuel that has accumulated in the exhaust from trying to start it. It can take a while to burn that off.

 

[CalienteJohn]

Injectors should be back in hand rebuilt by Tuesday or Wednesday.

Anything I can do in the mean time?? Besides soaking rings as mentioned

 

[the old grind]

I'd check the valve lash while waiting. Perhaps we won't need to pull-start this one, but do be sure the battery isn't drying out. A new starter for this surely costs less than a new battery. Just don't replace the wrong one first ... and DAMHIK, AKA BTDT this year once already. Doh!

 

[CalienteJohn]

Delays with the injectors being rebuilt and delays with me getting to the valve adjustments. Been SUPER BUSY

Anything else besides check the distilled water in battery?

Should I order a head gasket, head’s gotta come off for sure after injectors attempt right ?

Can’t pull start a hydro trans correct??
