Guest DJ Posted January 8, 2000 Share Posted January 8, 2000 uuuummmm how about nuffin... the cam shaft in these cars are driven of the crankshaft via a gears... the camshaft the drives cam followers which inturn push pushrods which push rocker arms which push the valves.... the only that may need adjusting would be the clearance between the rocker arms and valves... The only way these can go out of time is if you have a failure of the cam gears(highly unlikely and catastrophic) Quote Link to comment Share on other sites More sharing options...
Guest Subi81 Posted January 9, 2000 Share Posted January 9, 2000 Does anyone know exactally what years have Hydrolic lifters and what years don't. How can I tell if a car has hydro lifters. Thanks Quote Link to comment Share on other sites More sharing options...
Guest ShawnW Posted January 9, 2000 Share Posted January 9, 2000 The ones with hyd lifters have stickers on the valve covers. I believe any 83 and up 4wd with carb and 4speed would be the hyd type but not completely sure on this. Subaru seemed to use the mechanical lifters more on the non emission states I think but not sure. Quote Link to comment Share on other sites More sharing options...
Guest Whtspoke Posted January 9, 2000 Share Posted January 9, 2000 My '83 doesn't have hydraulic lifters, I think it was '84 and up. Quote Link to comment Share on other sites More sharing options...
Guest byb555 Posted January 9, 2000 Share Posted January 9, 2000 the hyd lifters started with the ohc engines. all gear driven cams had solids Quote Link to comment Share on other sites More sharing options...
Guest Skip Posted January 9, 2000 Share Posted January 9, 2000 Hey byb my 85 Brat EA 81 ohv has the stickers on the valve covers that Shawn mentioned. Are they Bogus ?? Quote Link to comment Share on other sites More sharing options...
Guest byb555 Posted January 9, 2000 Share Posted January 9, 2000 I would think so. I could be wrong. I have pulled down an EA81 motor from a 89 brumby/brat and it had solids. i also have a "Gregories" subaru manual that shows all EA81's as having solids. it also has the EA82 motors and shows them as hydraulic. please correct me if I'm wrong Quote Link to comment Share on other sites More sharing options...
Guest camosuba Posted January 9, 2000 Share Posted January 9, 2000 there are some hydralic lifter ea 81 motors about i have seen it was a jap importmotor but i couldn't tell you any more subaru tend to do things like that for no apparent reason Quote Link to comment Share on other sites More sharing options...
Guest Frank B Posted January 10, 2000 Share Posted January 10, 2000 Aren't hydrualic lifters more common on automatics? Quote Link to comment Share on other sites More sharing options...
Guest McBrat Posted January 10, 2000 Share Posted January 10, 2000 my 84 2wd sedan auto GL had solids, but both of my 86 brats had hydrolics... Quote Link to comment Share on other sites More sharing options...
Guest subrat Posted January 10, 2000 Share Posted January 10, 2000 i've never worked on an ohc subie engine before, but isint the whole point of ohc engines to reduce the complexity of the valve train? all of the ohc engines i'vworked on had no lifters or push rods. the camshaft acted directly on the rocker arms, which in turn act on the valve stems. as far as the 1-shaft engines, i have no answer, it seems that there was no definitive cut-off date for solid lifters Quote Link to comment Share on other sites More sharing options...
Guest byb555 Posted January 10, 2000 Share Posted January 10, 2000 I must apologise. I did a bit of research today and found out that what I said holds true for Australian motors but apparently some of the OS motors did have hydraulic lifters. I am told that there wasn't many of them but they did exist. Once again, sorry if I mislead any one. Quote Link to comment Share on other sites More sharing options...
Guest Muskeg Posted January 10, 2000 Share Posted January 10, 2000 My 83 had hydraulic lifters. The sticker on it said so, and when I took the valve covers off, there was no way to adjust them. The sticker underneath the hood will tell you the clearance required for the lifters, if it say "0", then you have hydraulic. Mark Quote Link to comment Share on other sites More sharing options...
Guest ShawnW Posted January 11, 2000 Share Posted January 11, 2000 Yep 86 GL hatchback has hydralic lifters. John Muirs book says : 83-84 Automatic Trans hydralic lifters 83-84 manual trans mech lifters 84+ has hydralic lifters regardless of model This holds true for my subarus so far too. 85 GL sedan had EA82 engine and hyd lifters 86 Gl Hatch has hyd lifters EA81 engine 4wd 84 GL Wagon has mech lifters and 5 speed trans.
