I am in the middle of an engine drop in my 83 GL 4x4 wagon. I am just replacing the old EA81 with a new one that isnt cracked and siezed.

 

The new engine has been throwing me a few curves but all in all it has been going fine. One thing though that I was worried about was a bolt that snapped as I tried to put the intake manifold back on. There are three bolts on either side that hold it to the block, would it be a problem if a side only got 2 bolts replaced??? I am not sure how much pressure is created there but it seems to be on there very well. Should I worry about tapping it out and replacing that bolt with a new one or savor the weight loss of just one more part subaru didnt need to have?

 

 

As well I have two large lines running from a can in the back of the engine to close to the oil filter... one threaded into the deal with the oil pressure sending unit... the other baffled me for a while I couldnt see where it had come from.... then I looked at my old engine and there was a makeshift hole drilled in the oil pan, and this line more or less glued to it. The new engine has no such hole.... I have a drill.... and some glue. Do it? JB that thing on?

I would definitely have that manifold bolt dealt with.. Very possible to end up with an intake leake if you don't.

Probably a good idea.... Good ol vice grips were able to get the stump outta the hole, I'll go pick up a new bolt and hopefully get this project finished today.

You definitely need all 3 bolts. It will leak over time if not right away. Intake air leak or water leak in the the intake side of the heads. Bad thing either way.

I would get rid of whatever it is they have installed to the oil filter and oil pan and go with the stock setup. That sounds like an oil cooler or oil filter relocation kit but I see no point in either of those on a carb model Subaru.
