Omega B Rocker Cover Gasket

[Patrick E. King]

I recently purchased only the above gasket for my 1998 Omega B 2L Petrol Ecotec X20XEV. On checking in Haynes later I noted that it is suggested that the 'O'-Rings be replaced at the same the same time and also that a recommended sealant be used in places. Are these always necessary in addition to the gasket? TIA Patrick

The BLACK sealant is necessary, it must be the black one since it stays flexible but some dealers are insisting it must be the green one. The green one is for the camshaft bearing end caps (metal to metal) and sets rock hard and is not suitable for the gasket. You need the sealant where the gasket turns 90% only and not the whole length.

You may get away without the new O rings at the bolt holes but they aren't very expensive and will prevent oil leaking up the screw hole.

Make sure you clear out the breather pipes while you're at it, if you don't want to be doing the same job again in a few months.

Thank you both for the sound advice.
