Evening all we done a track day at croft today in the 172 and had a slight mishap lol

Sarah over took 2 cars down the back straight and suddenly the car cut out, she bumped it off in gear but it sounded horrendous (rattling noise) and had no power then proceeded to cut out again. Car won't even turn over now just clicks when you try start it, also if you put the car in gear and try move it its seems like its seized solid. I personally think its spun a shell and locked up but does anybody else have any ideas please?

Cheers

 

It's probs just down to being French

 

Could be a possibility Gary lol seeing as 2 out of 3 clio's there today expired.

 

Aye? I thought they were reliable? I never got any grief from mine.

 

Ours had this problem and other one started over heating lol

 

snapped belt ?
broken cam shaft?

french?

 

Belt still looks like its intact

 

The bottom pulley could have slipped. They arent keyed and resusing the stretch bolt can result in failures. The F4R rarely goes wrong, its usually human error.

I would get a scope down a plug hole, see if you can see any issues.

 

So if that's the case i presume the rattling will of been the valves lol

 

Had a quick look this morning and looks as if engine is seized lol can't turn engine over by hand with bottom pulley.

 

that bit somes up dicko nicely....

 

Time to get the head off for a look

 

Fanbelt hasn't jumped off and jammed in the bottom pulley

 

Shame it wasn't me touching the belt this time Pete lol

but last week blacky fitted a new cam dephaser pulley.

 

Oooops. Sounds like the bottom pully or cambelt idler has gone

 

I've source a 50k mile engine with fully rebuilt head new belt all pulleys etc for £350 so not even worth trying to fix this one.

 

You can't go wrong for £350!

 

takethe head off yours

port and polish
skim for more compression lol

and put it on the new engine

job done

 

When you say the new one has had belts done, I would redo it while its off to make sure its done properly. Of the timing is out it will be down to about 140bhp

 

It's only done 5k since it was built, but looks like its been sold now anyway so back to the drawing board.

 

Any update on this Dicko?

 

yeah seized solid mate, we bought a replacement engine for £250 and sold the fooked engine for £100 lol. lad who bought it txt me to say he's stripped it and it had span a shell which blocked oil pump

 

Your not having much luck with cars are you dicko.

 

So the new lump stands you at £150. Not bad going.

Get the belts done and a good oil in there. I used Elf Evo 5w30. It was specifically designed for that engine
