Hi ive just finished a full top end rebuild. New big valve head, turbo everything and ive timed it up to what I thought was correct but it won't start. I've set the blue alternator pully so notch faces the 0 on the plastic cover and Pistons 1 and 4 are top.I've set the cam so the vernia arrow points to the little pin punched hole in the head and the woodruff key in cam points straight down. Is this correct?? When I stripped off the old head when the bottom end was at tdc for sum reason the woodruff key in cam pointed straight up,Everything I've read said this was wrong so I set it as per book. Am I correct or 180 degrees out?? Cheers Ryan

at tdc, the woodruff key should be pointing down.
I bet you have forgotten to put the little square washers under your rockers arms!

Gadget

When you stripped it down, the woodruff key was probably at the top as the crank needs to turn twice for the cam to turn once due to the pulley sizes so the bottom end could be at tdc while the cam woodruff key was upwards until the next drank revolution.

So should I have put the new head and cam in so the woodruff key was facing up as it was when I stripped it or would it not effect anything? I just thought with the bottom pully to zero, set the top pully so woodruff key is down and arrow to the dot. It won't even really try fire, there is a decent spark on all 4 cylinders. And fuel is there when you press the flap down although there isn't no pressure in the 4 fuel lines unless you press the flap down. I've not touched the fueling side of things tho and there was nothing wrong with that before the work so has to be the timing. Cheers

And no I defiantly put them in pal.any other ideas??

If it was timed up wrong before then leads would be in wrong place now?

I've put a new dizzy etc on her now and just set it so when engine is at tdc and piston 1 is at the top the dizzy is pointing to the top right to plug 1 then top left cylinder 3 then 4 then 2. Cheers

Multiplugs on the back of the inlet manifold the right way round?. Have you tried turning the dissy slightly while someone cranks it?. Also the little black plug on top of the dissy is very fragile, I had a similar problem a while ago, and it was a snapped wire inside it.

Chas

If it were me I would check the basics first.

Does the car have a spark at the plugs? Is it getting fuel? That should help pinpoint where the issue is.

Some success lads, ive been working in the dark double checking everything, the centre pin on the dizzy cap has come out and just the little spring was making intermittent contact. Secondly I had indeed missed a washer from under one of the rocker arms, I would never of thought of checking that so a big thanks to gadget. She has started up but it is too late to run her up to temp. One thing I have noticed tho the top ended sounded very tappy. Well like one really loud tap and then the others slightly tappy. The cam was already fitted to the head when I bought it and the tappets had been dry for a good 18 months before I gave them a quick 2 hour soak and fitted. Maybe a new set of lifters lads? Or maybe blocked oil pick up. I'll connect the oil gauge tmoro and see what presure I have, Hopfully that will tell me if the pump and pick up is ok. Some success tho lads so cheers

As above, we need to know at least this to help mate.

Bransby

Hi mate, she is running now. I did have fuel and I did have a spark on all 4 plugs.it turned out the centre pin on the dizzy cap had come out and I had not noticed and only the spring was making intermittent contact. Also like a dick rushing I missed a spacer from under one rokers. Thanks to gadget got that sorted. Top end is tapping now tho but I'll start a new thread for that when ive got some more info. Thanks again every1

Top end will tap for around 20 minutes if you used new lifters. They need to fill with oil. Just let it sit and idle for a while.

I don't think they where new but been sat like a year and half so I'll start her up tonight and run it up to temp and fingers crossed will quite down. Cheers pal

It really shouldn't, 20 seconds maybe, 20 mins is however the running in time for a new cam/lifter kit.

Bransby

I've run it up to temp and the tapping has quitened down hell of a lot but still a slight tap, sounds a little ruff on top end when you start to rev but not terrible like before, cam loves looked really decent. Not tested oil presure yet but no light on dash so it can't be too bad. Do you think new set of lifters or see how these go. I've got a set in a old xr3i head could i use them? Cheers

mentalasanything

Sorry, should elaborate: it will tap/knock hard for up to 30 seconds. After that it will produce a quiet tap that gets quieter over 20 mins or so. Depends on your interpretation of tap!

Don't mix and match cams and lifters, certainly not old with new.... They work harden together (20min running in period for starters) so the old will often tear apart the new.

Bransby

Thanks pal, I'll just run with the lifters that's in the engine then or buy a new set/complete cam kit when I get some spare money, think a set up is priority at min tho. Just a fair drive from Leeds to Motorsport developments. Will have to take it steady.
