Need advice from the RTOC with ref to a friends C1J engine GTT that has broken down tonight.

The symptons are as follows, the little R5 GTT sounds like it running is on three cylinders but on 1 of the engine strokes whilst it is running @ idle there is a clonk that causes the engine to vibrate ?(Quiet alot) The clonk sounds like it is coming from the bottom end. There is no loss of coolant and no mayo and all 4 sparks have good spark and are in the correct firing order 1342 the fault developed whilst the car was being driven there is also no leaks under the car. Any ideas?:sos:

:agree:

I did think bent push rod but it's not the same sound as when a push rod bends will check it still though.

Cheers for the advice though

if its not the pushrod, then take the plug out and start the car. if the clunk goes away, then suspect the big end bearing.

Turned out to be a snapped push rod and a bent push rod

:agree: yep it was Chris's car, I believe he has ordered some new pushrods so car will be back up and running very soon. I have no idea what revs he was doing as I wasn't their he managed to get the car to mine where the RAC came and collected

Maybe if you were on boost & the pipe came off, the sudden loss of power slowed the engine to fast & bent the rods , is that possible guys ???
