To pull or not to pull?
Posted 11 December 2003 - 06:29 PM
I have about 45k on my timing belts (93 Loyal EA82 105K), I
also have a profound oil leak coming from the front of the engine.
At first I thought the leak was coming from the cam covers, so
I replaced the gaskets (PIA!) as well as the PCV valve (I read here that a bad PCV was the leading cause of leaks). Replacing
the cam cover gaskets took care of 1/4 of the leaking. I am pretty
sure the main leak is comming from the drivers side cam seal
behind the timing belt sprocket. So my question is...which is
easier, change the cam seals and timing belts with the engine in
the car, or should I pull the engine to get to all this stuff. When I
replaced the cam cover gaskets, work space was way tight, which
leads me to believe that pulling the engine might be tha way to go? Any and all advice is much appreciated:D

A good possibility for the oil leak is the oil pump seal. If you're gonna get into the timing belts, there's no excuse to skip this. You can get an oil pump seal kit (O-ring, Mickey-mouse gasket, and shaft seal) for about $20.
You can do all this without pulling the engine. It'll be a bit tight, but the most you'll suffer is skinned knuckles and some extra cuss words. Put a piece of cardboard over the inside surface of the radiator, otherwise you'll end up dinging the fins and cutting your hands. Or better yet, pull the radiator (only 2 bolts) to give yourself twice the clearance.
Of course, it's a lot easier to do all this if the engine is out, but pulling the engine itself is a ton of work. Only really necessary if you want to put in a new rear crankshaft seal or clutch, or do head work.

The reason that chaning the timing COVER gaskets only helped a little:
For the oil to leak out of there it has to get IN there somehow... therefore the oil pump crank or cams are leaking so they need to be changed. The timing belts are old enough to change.
Other items you may want to change also: The o ring that goes in the side of the water pump where the tube to the radiator exits as well as the 90 degree bent hose that goes rearward to the heater hoses.

it ca be pulled with the clutch fan still on, if the electric fan is off already.
i highly recomment taking the clutch fan out first, then radiator.
might as well over haul the motor, pull it out and do the front seals, then the rear seal and clutch/front trans seal.
it would make a good time to de-gunk, put all new hoses on when going back in.
its not hard t opull a motor, it can be done with a come-along tied up to a rafter.
pulling it out now, will afford you the options of servicing other stuff as well
i like to pull a motor if i'm getting into seals and timing belts
timing belt alone i would do with motor in-car and with the radiator out.

Looks like I will go with the "remove the radiator, keep the engine
in the bay" method. I can always pull the engine if it gets to be
too much of a pain.
