Max Power Posted January 6, 2005 Share Posted January 6, 2005 I’m getting ready to pull the 2.5 out of my 97 OB to do some work, and have a number of questions I’d like to toss out there before I get started. 1) Valve clearance – I will be changing the timing belt, head gasket and adjusting the valves while I have the engine out. Should I measure & adjust the valves before or after doing the other work? 2) Valve shims – Are these things proprietary and available only from Subaru? 3) Valve tool – Keeping in mind that I am pulling the engine, will I be able to complete the valve job without the special tool? Do I really want to do the job without the tool? I have read that the tool’s main existence is due to the tight clearances under the hood. 4) Removing the intake – My manual says to pull the intake before pulling the engine out of the car. I have read a few posts on here and have seen numerous pics of Subaru 2.5 engines that were pulled with the intake on. Anything I should be cautious of when pulling the engine with the intake still on? 5) Seal remover tool – I will be replacing the cam seals and as well as the crank seals. Is a special tool needed for either task? Most of this stuff maty have been addressed at one time or another on this board, so I apollogize in advance if missed the answers somewhere else.

Should I measure & adjust the valves before or after doing the other work? You will measure clearance before taking off timing belt, or at the very latest before taking out camshaft. You will fix clearance by changing shims when you put the camshafts back after reinstalling the head. 2) Valve shims – Are these things proprietary and available only from Subaru? As far as I know. They are 4.50 at 1stsubaruparts.com that I am pulling the engine, will I be able to complete the valve job without the special tool? Do I really want to do the job without the tool? I have read that the tool’s main existence is due to the tight clearances under the hood. No special tool required. if you do head gasket, you must remove camshafts and old shims, just replace with new shims. 4) Removing the intake – My manual says to pull the intake before pulling the engine out of the car. I have read a few posts on here and have seen numerous pics of Subaru 2.5 engines that were pulled with the intake on. Anything I should be cautious of when pulling the engine with the intake still on? You mean intake manifold? No you don't need to pull it out. 5) Seal remover tool – I will be replacing the cam seals and as well as the crank seals. Is a special tool needed for either task? For removal, camshaft ones will automatically come out when you remove camshafts. Cranshaft seal will come out with oil pump if you reseal it. Rear main seal - I used a screwdriver. For putting back, see my post. Most of this stuff maty have been addressed at one time or another on this board, so I apollogize in advance if missed the answers somewhere else.
