FSM Mystery miss.

Put serviced injectors back in the super major, set tappets, changed fuel filter, washed out sediment bowl on pump, bled system turned her over to make sure juice was at each injector, tightened injector lines, and fired her up.

Still misssing terribly!

cut in once or twice, but only for a moment.
Lots of smoke.

Cracked injector lines and one cylinder is "off"
still.
Thought it must be a valve or cracked piston.
Took head off.
Took out the valves on 'missing' cylinder.
Valves a bit spotted on the seats, but I've seen worse.
the head could do with a de-coke, but again, I've seen worse, and not gummed up with oil, in fact a good warm up would get rid of a lot of it.

Pistons all appear about the same, none with more slop than any others. Would cracked skirt make it miss?

I need some advice here chaps.
Planned on using it this spring!....and spring's springing Fast!

When I cracked open the injector lines with it running, the squirt of diesel appeared about the same from each line.

Could rings be so far gone that it doesn't fire?
If so, you'd think more oil would be "upstairs" than there is.
Could it be the pump?

If it is, I'm a bit ticked for pulling the head.
(There again, valves could do with grinding in,...)

What do I check first, fellows?
What did I miss??

Thanks in advance!!

Richard.

Thanks for the offer on pump info!

R.

I'm thinking you might be right about the pump, Mike.
In a way, I maybe pulled it apart for nothing, but I'm glad I did. It's a good engine, and am pleased I didn't put it to work with the 'foreign bodies' in the bearings, and the dirty valve seats.

Got to find the closest, cheapest, and fastest parts now. (Probably here will be the cheapest!)

Thanks again,

Richard.

Thanks!

R.

First off, thank you for the information supplied in the other threads.
I would have replied, but feel a bit embarrased by the amount of posts I'm wracking up!

It has no rotor caps on the exhaust valves, so that's one problemit hasn't!

Re. the rad. cowl, think a pal has one for me, when he has time for me to go and see it. It sounds scary to buy a new one these days!

Thanks for the info. re. the driver's manual. It sounds like a "must have"....as well as the I&T.

Thank you again for the ideas, I'll let you know how it goes.

R.

Still, if it was timing, how could 3 fire and one not?
Compression on back two cylinders appeared less than on #1 and #2.

I am very interested to hear any ideas!

Richard.

Thanks again for your thoughts on this, they are very valuable to me!

I too am thinking low compression/ shot rings or some such.
It's a good idea you have, to chuck valves in lathe to see if they're bent. I'll try them and see.I don't think it was a carbon on valve problem, or a loose valve seat, I scraped around the seats on the 'dead' cylinder, and they seem ok.
Will grind the valves in and this morning before the day gets too old I'll pull out the piston and see what I have,
It might just need rings, or maybe the whole shooting match. Depending on what I find, I might have to pull them all out , and it's a good time to check bearings as well....

Still, it's worth doing right, but a bit inconvenient to do it Now!
I'll get back to you on what I find.

Thanks again,

R.
