UK	Had a PM from a member, which I can't answer at present so if anyone can help Steve out it would be appreciated: Originally Posted by Bourbonmog Graham, I met you at the factory in 2019 before we shipped our Morgan back to the USA. I've really enjoyed the car and have been collecting maintenance parts. It looks like I had better prepare for a head gasket at some point. My engine number is throwing me. Engine: 20H E23 100585 Car 91 Plus 4/M16i (Dec build M8484 chassis). The E23 doesnt seem to be consistent with any part manual. Should I be looking for the Rover 820i 90-91 head gasket and engine rebuilt gasket kit (One for easy/one for total disaster). Any advice on a part number is appreciated. I know I don't want to use the T16 gaskets but it looks like there is also a difference before 1990. Hope all are doing well there. We are going to try to come back over again in 2023. I'm trying to convince my wife that a prewar-flat rad is a totally different car that I need to purchase to drive over there again.

Didn't know they had a USA helpline number until I looked just now. Graham (G4FUJ) D8921 L44FOR '93 4/4 Giallo Fly 2 seat '90 LR 90 SW '06 Saab 9-3 Convertible

If using the later multi steel gaskets you must remove the oil restrictor in the block. I did not know this when using the new type gasket but as I use 5/40 oil I found no problems after 20,000 miles. But! To remove the restrictor use a self tapper into the supply hole from the block and pull out the tin restrictor. Advice to your Morgan friend if fitting the normal gasket use a little gasket sealant around the oil supply hole for the camshafts as this is a oil leak problem on all these engines. However our Morgan has covered over 177,000 miles so the basic engine design is sound. Dinko
