Big Problems with an RD28, Need advice Please

Cool. First job in the morning ill check the plugs. There wasn't any white smoke. What's "drowned? Like submerged in water? If that's what you mean nope it was never drowned. I did have it running it started fine just had a clunk going on. I took it round the workyard and everything seemed fine exept for that pretty prevalent knock. Now she doesn't wanna start. Mmm more diagnosing in the morning.

I remove the head will I need a new head gasket?

Got my workshop manual coming on tues.

Its all a Bit of a shitfight but I'm really enjoying it :D

By running it with the timing out, you may have bent a valve, you may have it timed to squirt no6 instead of no 1, this will cause bad knocking and hard start if at all.
Head removal is new gasket and new head bolts.
Take the belt off, start from scratch follow my lead and we'll get to the bottom of it.
Driving it could destroy it atm.
Cheers Rod.

Hey ferret, when I fitted my belt today the manual says to be at bottom dead center.... Not sure if this helps.

Bdc Keyway on the crank at 6 o'clock.

Yes but the piston no 1 must be at top dead centre, both valves for that cylinder closed and injection pump to have just squirted to no1 injector.
(Loosen no1 injector line, ignition on, rotate pump drive clockwise till it squirts.)
Fit the belt, rotate motor to key at 6 oclock, check markings, adjust by only rotating cam or IP but they should be close.
Keep fingers away from fuel line as it's high pressure and can penetrate skin and kill you.
Tighten injector line.
After checking belt markings, tighten and rotate motor by hand 4 revolutions.
If all free, fit lower timing cover, THEN balancer and top cover

You must remember to loctite the crank bolt when you are happy with it all.

ok this is a new motor
has new glow plugs,injectors the lot new pump also !

i know nothing is in the cyl as i have pulled the cam out and rotated the crank without any dramas!

hey ferret
on a new motor it shouldnt mater with the crank as long as the woodruff key is at the bottom
it is the cam that dictats the firing cycle so to speak ????
if all marks are lined up i should be able to turn over by hand ,but cant

Ok, I didn't know it was a new motor, yes the cam dictates the valves, with the cam timed it should be free to turn.
As I mentioned before, the injection timing will effect starting and can cause knocking if it's out.
SO, if this is a new motor, I would be talking to whoever threw it together, as I feel they have done something wrong.
Can't think what it would be, and a new motor should not knock.
Cheers the ferret.

Your spot on here, whether it be petrol or diesel the principles still the same.

After having a read I like you would be now looking into other things ie: the cam for starters.... Is it the original cam your using or a replacement?

The only other thing I can think of is that the pistons are around the wrong way, this could cause conflict with the valves!

Damn!!!! That would suck! Ghee got some merit though. The valves would be very unhappy with that!

Yeah, well it's the only thing I can think of, it wouldn't interfere until the camshaft went on.
I had a motor rebuilt years ago by a very well known mob, pistons around the wrong way.
Cheers, the ferret.
