Default Engine Overhaul

Finally came across some cash, so I ordered myself a new clutch. Im going to pull the motor instead of dropping the trans to do it (I hate straining my neck under the car that much). My car has 167 thousand miles with a mysterious past, so while the motor is out I want do all the possible maintenance things I can without splitting the block (my engine experience ends at removing the heads). I need some help figuring out exactly what all I should do. Also, would anyone recommend doing the head gaskets? I don't know if they have been done.

Working with a 95 ej18

-Timing belt
-Water pump
-Oil pan gasket
-Rear kidney plate
-Trans input shaft seal
-Rear main crankshaft seal

Have things to add?

cam seals, valve cover seals/gaskets, coolant hoses, exhaust gaskets that are removed, timing belt tensioner and pulleys, oil pump seals. do they water pumps need service/replacement unless they have failed?

if it ain't broke....

You could replace ALL the gaskets if you want, but if they're working fine...why? Take a look at the front main seal as well. I daresay you should remove the oil pump and check the screws on the back to make sure that nothing has backed itself off. If you're really ambitious, you can check to see if the output from the oil pump lines up properly w/the input to the block.

I'm not familiar w/the 1.8L heads, is there any valve adjusting to do there?

I'm prepping this car for rally cross and am going to put it through heavy abuse. I may be wrong, but don't the hla's need to be refilled with oil after some time?

no, kinda, the oil in them is part of the oil that runs around in the motor in reality it changes with each oil chance all on its own with time

ether you have good or bad hla's but if you take them out you are supposed to re oil them or it will take a few hours* of the engine running to get them @ 100% again.

* not too sure on the time

also see if you can find a 97 -98 ej22e they have SLA and reduce some of the effort it takes to turn the camshaft*, but they do need adjusted every 100k

*subaru changed them to get better mpg along with other changes in the 97MY
