September 2, 200520 yr I have a hell bad rattle in my 92 brumby. it sounds like tappets so i adjusted them but they are still noisy what do you think? Stock EA81 with extractors, no cat and 2 inch hi flow system
September 2, 200520 yr Get a Mechanic (needle) Stethiscope and find where the noise is really coming from.
September 2, 200520 yr Author spose i can do that tomorrow. by ear it definatly sounds like tappets and from that specific top of the head area
September 4, 200520 yr could be like my rx, the little pin for the hill holder cable rattles like hell. i thought it was a lifter till i put my finger on the pin, then the engine was quiet again.
September 4, 200520 yr Did you check the push rods? was one of your tappets loose? if so check these as they do bend.
September 4, 200520 yr Check your oil pressure - the EA81's do need oil pump replacement after 100 - 150k, and you might have air in your lifters. A lot of people will just replace the seals in the pump, but really once the seals are dead and crispy chances are a new pump is needed.

September 9, 200520 yr Yes over here at least the turbos, autos and maybe the later model EA81's a lot had the hydro lifters. On my turbo EA81 I used to have there was a sticker on the valve cover that said something like "do not adjust valves" or whatever. If you used guages and set a hydro engine like you would a solid lifter engine you might to have some noise. One of the experienced EA81 guys ought to be able to tell you exactly what models/years got the hydros over here, and what is different on the procedure to set them, as I'm not sure on that.
