Re: excessive oil pressure on fresh engine rebuild
Are you using aftermarket head bolts? They sometimes restrict the oil flow to the clylinder head. The kits typically have one bolt with a reduce shank and under head radius for the oil port location. Dave W

Re: AE86 ride height adjustment
For the setting up, ride height you need locate the car on four level pads. Your typical garage floor can easily be off by a 1/4" [cross-car] plus the floor will slope towards the doors. You need four pads, with the appropriate pad shims leveled to within a 1/16" or better. Mark the floor ...

Re: lifter notch and shim replacement tool
I have to agree with Jondee86 when it comes to holding down the lifter buckets. It is a PITA to hold down the edge of the bucket the tool. If you have more then a couple shims to adjust, it is much easier to lift the cam. If you do not have to adjust the front valves you can actually leave the belt ...

Re: valve buckets loose
There is another possible cause. Check to see if the cam has shifted f/A and is centered over the buckets Vs offset, which would cause the bucket to slide up/dwn Vs rotating. There could be enough tolerance is the cam lobe core to affect just a few buckets. Dave W7

Re: valve buckets loose
You be $crewed! If you had a rare engine, a machine shop could actually sleeve the bucket bores. Time to look for another used head in better condition. You need to find what caused the problem. I would do a close inspection, of the current valves, springs, keepers, relative to cam spec's, before sw...

Re: Kitsunami's 86 SR5 to GTS swap
As old as these 4AGE engines are, you would be lucky to get a good short block from a pick and pull. I would look at getting the crank turned [probably $90] that way you know you have a good bottom end. Do not but bearings until to get the crank back from the machine shop. Dave W

Re: Horn don't work help?
Use a test lamp and see if you have current going into the horn. If you do not see current at the horn check the fuse. If you do not see current, in either of these cases, you have a problem with a plug connection or a broken wire. Odds are pretty low that the horn actually stopped working. Dave W

Re: Build question
You normanlly modify the piston Vs the head. You would not want to countersink the valves into the head which reduces flow. Typically those mild duration cams are not any problem. It's the lift [ ck spec's ] of the camshaft and that would require the piston needing a relief in the valve pockets. If ...

Your oil pressure sensor is located right under your distributor. Clean and tighten the electrical connection.
Odds are a lot lower that it is a pressure relief valve. Dave W

Re: AE86 SR5 Rear End?
The SR5 rear axle is more the adequate for a stock 4AGE. The SR-5 axle [S series 6.38 ring gear] will have a 3.9 ratio or a 4.10 axle ratio. The axle is probably the 4.10 since the original car was an automatic. This ratio, actually better suits the power band of the 4AGE engine. Dave W

It would be a lot more work with a 1/8" gap. It would be a 2 man job. You would need a 2nd person holding a copper block under the panel gap for each tack weld. You could only do a few tacks, then have to move to another location. The easiest method to reduce weld distortion is to cut a larger ...
