I have been reading up on the powertrain K series, which I believe I have in my car. Does anyone know if the 1.8 VVC is the same engine used throughout the MG range. Also can anyone help me with instructions on how to change the cylinder head. I've checked the Haynes manuals and there isn't a manual for the 1.8 vvc 160 just the 1.8. Please help.

Hi and welcome to the forum, I'm sure that some VVC nut will assit you further, but yes, the VVC engine has been used in the F, TF and 25 and ZR vehicles.

Just out of curiosity, why do you want to change the cylinder head?

Well the cylinder head gasket has gone, theres a little jet of water shooting out between the head and the crankcase. But wanting to do the job myself, with some help of course, and would like a bit of help, as there is no manual for this engine.

Thanks for the reply Rincewind!

Thats okay, everyone hates a smart arse anyway!
I presume that the VVC mechanism makes not a lot of difference when taking the head off as one complete unit, as it doesnt matter whats in there, whether its VVC unit or a standard set up.
Re-timing might be different, I'll stop guessing now and let someone older, wiser, and with dirtier finger nails set us straight!

Timing a VVC engine is no different to timing the normal K16. I would however make plenty of checks when re-fitting the cambelt and also pay close attention to the relationship of the small timing belt at the flywheel end of the engine to the main timing.

The cylinder head bolts and gasket follow the same procedure as the K16.

It would be wise to renew the main cambelt, the cambelt kit should include a tensioner spring that is only used for initial tensioning and is removed once all the various bolts have been torqued correctly.

Good chance that the VVC mechs will have to be removed and refitted due to a head skim requirement by the sounds of the severity of the failure.

As long as the mechs are put back together properly, you are most of the way there.

Loctite the cam sprocket bolts into place whilst it is being re-assembled as this is a failure point.
