Title: timing issue
Post by: gazvenn on March 07, 2011, 10:51:20 am
real quick question: is it possible for a 1.6gtd engine to run when the head is 180 out to the flywheel cos the only mark i've found on the flywheel is exactly 180 out from the camshaft. or can the flywheel be fitted wrong?

I suppose its possible, not sure if its possible without engine damage. People have been known to put the flywheels on wrong, however.

its impossible to get the engine 180*out from the cam, because its 180* out every other rotation..

turn the engine another rotation and check the timing marks again ;)

right cheers, thought i'd check as it seemed strange to me. having issues since putting the engine in was running and sounded ok but tried driving it and when putting into gear itd just sort of bog down and stall. does this sound like it could be down to the fuel pump timing as from what i've read thats the only real idea i've got at the moment. just need to find an adaptor for my dial guage to try set everything up right.

i would be guessing a fuel supply issue, more than timing..

because if it starts easy when its cold, your timing is close enough for it to be driveable..

i was having fuel pour out of the return line going into the pump but a quick trim and that seems to be sorted and still same problem. what sort of issue with fueling are you thinking? too much/too litle?

didnt start that easily seems to take quite a bit of cranking when cold but warmed up slightly it fires up straight away

that makes me think its a fuel problem even more..

i think you got an air leak in the fuel line, a bad fuel filter, or a bad pump shaft seal.

now, im basically positive your problems lie in your fuel system..

(your pump is being starved of fuel, plain and simple)

Sounds right to me, too. This is often the result of a plugged fuel filter, though a nice big air leak can keep the pump from sucking enough fuel to pull out of its own tracks.

well i've got a new filter im yet to put on so that'll go on tomorrow and i'll have a check of all the pipes etc at the same time.

thanks a lot guys and very impressed at the quick replies, usually takes forever to get anything even remotely useful on 90% of forums

i'll update tomorrow how things are going

well tonight i've worked out that the engine timing is definitely sorted. and had it running again after changing the fuel filter. Also turned the pump up a bit as i remember the lad i got it off saying he'd turned it down. now got about 3 threads showing on the stud at top above the nut.

still having issues with power going forwards seems to be pretty much fine in reverse just bogging down and trying to stall going forward in 1st.

just for some more info the car is an 83 golf diesel (1.6 n/a originally)

should i look at turning the pump up some more?
 
also i'm not 100% sure where the ignition timing is could this be causing a lot of the issue?

wondering if its something to do with clutch seeing as it seems fine in reverse just not forward?

thanks again,

Gaz

well, problem solved on the fueling front. timing was way off and now runs ok with no smoke still need to fine tune the advance etc but was good enough for now.

New issue though, took it for a quick spin and the clutch is slipping loads, got it back on the drive and got a lovely whiff of it then popped open the flywheel peep hole and a ton of smoke came out. soo... whole lots coming out again tomorrow morning to see what the beef is.

gonna try to support the engine on something and pop the box off the side without taking the whole lot out again as i havnt got my mates hoist at mine anymore.

if you keep the passenger side engine mount connected, and drop the other 3 mounts, you can support the oil pan with a jack, and drop the engine down enough to get the trans out..

True;
but pump to cam out by 180* is possible, due to pump to pump pulley assembly error is it not?
 Not relevent in this case it would appear...

This is possible and it will run with the pump out 180 of the cam...it just doesn't run well.

yes, you can get the pump and cam out.. the pump sprocket and cam sprocket are the same size. so if you turn the cam 1 turn, the pump also goes the same 1 turn, not 2 turns like the engine..

every other stroke, the engine is 180* out from the cam and pump..

so, if your crank is 180* out from your cam and pump, all you need to do is rotate the engine one more turn.

all seems to be sorted now, popped in a 210mm sachs clutch i had lieing around along with the flywheel from my 2.0l gti engine sitting in the garage. took her out for a spin and seems i left 1st gear on the drive somewhere as its impossible to engage. new gear linkage kit in the post  ;D
