Hi All,

My friends MK5 gti failed to start during the week, and on inspection it appears that the engine will only turn (by hand) a 1/4 turn either way then the pistons touch the valves.

Garage cant explain why this is happening. They fitted a timing belt and pump 18mths ago and the timing chain and tensioner last autumn. All using genuine parts.

without being cynical and doubting their work, is this timing related? they advise all seems well with the timing on either side.

Engine Room in Motherwell guesstimate a possible bent crank, quoting £3k for a rebuild.

Does anyone;

A) Know with the symptoms detailed above if the diagnosis is accurate or what it could be?

B) where would you recommend to take on the work / strip down to diagnose and repair?

C) where would you recommend for an exchange engine to be supplied and fitted?

Any help would be greatly appreciated as mega bucks repairs are on the cards either way.

cheers! :rthumb:

If the pistons are hitting the valves I would say yes timing related either way.

Cheers, it does sound like the only explanation

Anyone else any input? These engines dont seem to live uo to the old 1.8t in the reliability stakes

Main dealer has confirmed timing is fine and no associated parts have failed causing the above symptoms.........

What a nightmare.

Is this likely to be due from clogged pick up pipe starving the pump?

Supposedly there was a recall of the early mk5 gti's to have a stronger bolt fitted to mount the sprocket to stop it failing. asking him to check for a recall, but not counting any eggs at the moment

I have also asked for them to pour the contents of the oil filter through filter paper to see exactly how much particles are floating about, as anything bigger than the gauze on the pick up will still be in the sump. was some big chunks along with the sprocket in there, the potential swarf being the concern. dealer advised new engine, turbo and intercooler.

asked to price up an oil pump, chain and pick up pipe if the above doesn't look overly bad, as it seems the chain snapped along with the sprocket on start up that morning, as no head or piston damage has occurred. pick up pipe could even be cleaned, didn't look bad in the video they sent.

if the above gets fitted, throw in some engine flush, magnetic sump plug, oil and filter. run it up to temp then dump it. do this a few times if It lives then its hopefully game on! :laugh:
