[The Cambelt Kid]

Hi Guys,

I've just changed the cambelt on my 2.6 and when i first cranked it over aftger the change it made a ticking noise, not too loud but certainly not good at all.  I installed a genuine kit and followed all the instructions in the DVD.  I took the time to make sure the timing was spot on, i think i ended up manually cranking it over 15+ times in the end...

Now when i first put the belt on and then cranked it over i forgot (like a total fliocking idiot) to tension the belt, which caused cam 1 to slip 4 teeth. (gulp).  Now being a clever dick i manually moved the cam back the the original position.  So all in all the crank was TDC, cams 1+2 was nob on and 3+4 was ever so slightly to the right hand side on the cam marking on the cam timing tool, the timing mark was still inside the cam marking though.  Maybe i#m just being a bit fussy, but i really wanted the timing to be spot on.  Anyhow i cranked it over by hand quite a few times and didn't feel any more pressure than i usually would.

My question is... What damage can be caused if the cam slipped as it did?  I never ran the car with the timing out, so i'm hoping that i've not caused any damage...

I'm on the verge of being out of my depth now so i might even start begging for a visit

In fact i really feely like    I've really mucked up this time!

I guess the only way to tell is compression test.  Hopefully you've got away with it.

Can it really be that bad?  It's not like i drove at 50mph and then it went bang, at most it was ticking over.

I think my dad has a compression tester.  So i guess i will have to manually crank it over and compare each pot?

It ran ok on tickover and didn't cough of splutter, just the usual hum with a ticking noise.

[Dazzler]

Are you sure the ticking was not there before, ie- injector tick..
Have you tried pulling the camcover whilst its running to see if the tick gets worse or better??

[The Cambelt Kid]

Pulling the cam cover?  The noise sounds like it's not timed correclty, even though i spent an age getting it tip top!

If all the cams are on the timing mark and the crank is TDC on the water pump, surely this it how it should be.

Is it possible to damage the valves by one cam slipping when manually cranking over?  

[Dazzler]

Only if you force it, otherwise most unlikely.

[The Cambelt Kid]

Well i guess i could have done then.  I was cranking against the compression of the engine and putting in a few grunts so i think it's possible...    

Come to think of it, it would take a breaker bar and one hell of a push to force a valve into a pot... wouldnt it?

What's the score it i've f***ed it?

New valves if the guide's are OK...

but look on the bright side.

If I were you, I would get that cambelt cover off, and be double checking EVERYTHING... sometimes you can get strange noises if the water pump pulley etc doesn't sit right - we had this on Hotel21's car a few weeks ago

Once cam timing again confirmed as spot on - and it's been cranked by hand, see how it runs. You may have got away with it.

At this point, once confident timing is fine, I would be compression tested.

If compressions are OK, power seems ok, see if your noise settles down. Might just be a dry follower.

Can you confirm - did you RUN the engine with the tensioner backed off? (I really hope not!)

If you need a visit - then you can consider me as an option, but I DO have some time constraints and other pressures at the moment, so I don't have a hugely open diary...

The only time i ran the engine was after the timing was spot on and all bolts were torqued up.  I didn't want to run it while the plenum was off so when it was started the car was back in one piece.

I'm interested in how Hotels water pump sounded, was it that bad you thought it was the timing?

As i say it was timed up and tourqued up before running.

Timed up... torqued.. and tensioned? I that case, if you didn't force it by hand either, I think you should be alright...

[The Cambelt Kid]

Thanks for the offer James, where are you based?

I will triple check all items before calling in the A-Team, so as to waste your time.

Cheers

Still not clear if you ran the engine with the tensioner not set right.

Tentioner was adjusted and torqued before i even put the key in the ignition.

Just to re-clarify, from my understanding, would you agree that it'd take a breaker bar on the crank to bend a valve?

I think you'd be unlucky to damage, but compression test will confirm.
