what gasket for a hte engine

Post by Greyreaver » Wed Jun 16, 2021 7:20 pm

Hi I'm thinking of taking the head off my '83 rialto for a clean and to give it a good checking over (two of the spark plugs keep looking oily ).,and I was hoping to have the gaskets ready before I start. She has a yellow rocker cover and the e stamped on the engine & the engine number. Looking online for complete gasket sets I'm getting confused some state not for the yellow top (fair enough ) others claim to be for all the Rialto range upto 1990, some for leaded engine & others unleaded. Can anyone recommend which set to go for or supplier to contact please

The so called unleaded engines had different valve guides with a narrowed top section and used different oil seals which were “top hat” shaped and held in place under the spring. Usually green in colour. Your E engine just needs a standard set.

The only other difference will be the thickness of the head gasket. The thicker type is normally recommended for the 10 to 1 head so the compression ratio isn’t increased too far. The gasket with a bead of red sealant is the thinner type. The thicker type of gasket is normally just grey in colour with no sealant.

Theirs two types of head gasket sets unleaded and leaded

The only difference is the valve stem seals that are included, all engines before 1990 are leaded type and after is unleaded type

theirs also two types of head gasket, the yellow top used a thicker headgasket but you can also use a standard one if you wish

Thanks I'll get on with it now. The old girls developed a oil seal leak now so no excuses not to, was wondering if reliant made anything designed to be worked on by humans,cos I never seem to have enough arms and I don't have the spine of a python. But then again if it was going to be easy somebody else would be doing it.

If you have the time, sometimes its easier just to drop the engine out and work on it. the engine sits nicely in a decent workmate.

Remove the manifold stud near No 6 stud hole as they can bind and don't be surprised if the motor has to come out. positive side is you can give it a bloody good clean.

You need to get the car up about 2 feet and lower it onto a bit of carpet to drag it out and it is a two man job with a bit of two by four across the engine bay. If you can borrow an engine crane it would be a great help.
