Just got some gaskets for my engine
, identical to yours. I used either one of the following, and they have a large range of Perkins parts:
Perkins 4154 and Perkins 4154 / 200 Series - Parts Supply Corporation - EngNet
Perkins 4.154 engine overhaul kit
Gaskets are not cheap! I just had to remove the heat exchanger
(Bowman also) and I had to pay about $60 for the 4 exhaust
manifold gaskets. I make my own main exhaust
and that seems to work fine. Sometimes I'll make my own for low pressure areas and if dimensions are not too tight/critical.
Good luck with the 4-154. I'm very impressed with it's longevity (1982), runs like a watch after 4+K hours, and all the people I've talked to say its well worth keeping it in the boat as long as I can get any parts needed. The only mechanical problem being that it's English
therefore has rear oil seal
slow leak. Never enough to notice drop in engine oil
level but requires diapers in the engine pan to keep cleanup simple.
