Valve adjustment trouble

Hi peoples

A mate is having trouble with his valve adjustment. The engine is a EA81 Jap import, All the valves feel a little springy when you push the pushrod down but one goes into the engine a lot more. Do these jap import engines have some sort of hyd lifters and what would the setting be for the tappits and why does one have a lot more play so when you push it down you get about 2 or 3 mm clearence.

Any help and ideas as soon as possible would be great as he needs to get this thing running

you can ring me on 0410920488.

Thanks heaps

Marc

Some EA81's had hydraulic lifters, sorry, not sure which ones. I'm thinking 85 and onwards?

The Jap imports with a little sticker on the rocker cover were hydraulic.
Hopefully your sticker is still there but yours sound like hydraulics.

Subaru say they did not sell any EA81 cars in Australia with hydraulic lifters, so they can't sell you new ones - no listing. We have been importing used engines for at least twenty years from Japan so you could find anything in these cars now. The pushrod that goes in a bit more sounds like it collapsed/stuffed. Why is ya mate checking them in the first place?

hi peoples

he is checking them as he just got this engine to go into his car and was checking the tappit settings while he was checking the rest of the engine over after putting it in the car and being an unknown engine to make sure all is ok, and not thinking it would have hyd lifters.

ah,ha, can't blame him for that. Hydraulics ? might just pump up nicely with start up or soon after. My Ea82 turbo ones did after being left on their sides for a long time, which is a no-no. store 'em upright in oil, hard to store 'em upright in an engine that keeps them on their sides ?!?

thanks 90brumby but I think if it comes to the stage that we split the case we will throw the hyd lifters and replace with solid ones.
We are going to set all the tappits to where they are just touching the valves and see how that goes, the engine has been sitting for about 18months so hopefully it will come good.if no luck with that we will strip it down and rebuild it.

thanks guys for all your input and ideas. I will post how it goes.

my hydraulic adjustment method with OLD FORDS was to adjust as you say you gonna do, then at op temp eng stopped adjust so the pushrod just swivels freely , not tight, not loose between lifter and rocker.
