Looking good. Happy to advise on how to sort the headlight condensation if you need.

Great looking car, great colour also :wink:

That looks far too good for what you paid - well done.

Thanks. It was a good buy. Few jobs to do. I followed advice and checked the disa valve and low and behold it was loose and the paddle had a lot of play.
I have ordered a rebuild kit.
Whilst I am there i will give the car a service and change plugs and rocker cover gasket. On that note, I have read online and on here and noted some debate about the need to use rocker cover sealant either end of the block (on the half circle sections).
Have any of you gone down the route of using sealant and a gasket? Or would a seal that has been correctly torqued down in the recommended sequence suffice?
I am going to see if colb will be able to meet me this week to guide me through a health check and compose a list of jobs.
Thanks

Only a week or two back I replaced a leaking rocker gasket for another forum member. It was only done 18 months previously by a garage but was leaking quite badly. We found it had no sealant on the half-moons. You only need a small blob in the corners where the gasket does almost a 90 degree change of direction.
We also found they had re-used the original seals that go under the bolt heads. These were completely deformed and several were letting oil by.
A good quality kit should come with new ones though.

I will definitely do that then. The kit i have got seems to have the bolt seals. Ans i presume seals for the coil packs.
Silly question, did you put the sealant either side of the seal, a dab on the block and rocker cover with the seal inbetween?

Fit the three seals into the top cover first. Then put a small blob of sealant at the base of each half moon on the seal. That's all you need.

Good tip. I will give that a go. Thanks

It will be obvious when you look at it. The rubber seal has a sharp change of direction at the base of the half moons. Blob the sealant there.
