Something has happened to my valves.

The car pulls great then all of a sudden it starts to missfire like a pig and then returns back to normal.Theres no telling where when or why it happens.

I did a compression test and no 3 and 5 cylinders are down to 60psi allthough when its running well you would never believe it.

I think its time for a new engine :headvswal

And this one has only been in a couple of months :cry: :cry: :cry:

Are you sure that you don't have a coilpack on it's way out and the poor compression results aren't caused by bore-wash?

Hi Si no because sometimes a get a horrible cam knock as though the valve is stuck open.And ive changed all the conectors.

Is there no warranty on the engine then?-did you do it yourself?

Im begining to think the belt might have slipped a tooth whe i was fitting the lightened flywheel.

Yes i did it myself allthough no internals were touched.Just new tubs,downpipes,injectors,lightened flywheel and manual conversion.

Bummer!-engine out again then, gonna rebuild or a new lump?

P.S, why would the belt slip when fitting a flywheel? :confused:

I know where theres a lump thats had a load of head work done after a head gasket went and he rebuilt it (with loads of pis of rebuild)And i think the guy ran out of money or patiance so hes selling it for £600.

So i think this is my best option while i rebuild mine.

Is that for a complete engine then?-just thinking that yours could help Si out if it's only top-end?-could benefit both of you, just a thought! ;)

Yeh complete engine good tubs,alternator the lot.

I was thinking of putting my GT28Rs,555s,flywheel and U/D pulley straight on and dropping it in.

The problem is i go to Canada at the end of the month (back to work)So i wnt to get it sorted before i go.And when i come back ill have a few$$$ toplay with so could do a bullit proof rebuild and change again ;)

It may have been turned backwards when changing the flywheel and slipped a tooth.
