the motor has had a noise coming from the left cyl. head eversince I put the car together. it runs well and now has 12,000 miles on the motor and the noise is still there. not much change.

Today I was checking the timing and when I losened the dist. the noise changed.

I would hate to put in a new disty and still have the noise. Has any one had any thing like this happen? solutions?

 

this is on the 87 gl10wagon ea82T

alrighty then guess its just my car. I will swap some parts and see what hapens.

Was the engine out of time? I assume the noise returned after you verified the timing was set timing properly and tightened the distributor again? Id say its the bearing in the distributor shaft like you are guessing too.

No need to replace the disty - it can be repaired. I got mine done locally for $55 - that included a rebuild of the vac advance. I think it was only $35 to have a new bushing put in.

GD what were your symptoms? did you have noise?

 

ShawnW timing was ok, I was just messing with it. I bumped it up 2 deg. and now it pings.

 

I need to put it back tonight after work. I am a little pissed at distributors right now. I am having a terrible time tring to get a sonoma at work properly set. I neglected to mark the crank position when dissassembling now its all back together and wont fire properly:mad:

 

but thank you for the response guys.

did you have the timing belts off? maybe the tension is not tight enough, and the belt has slap, making a noise at the distributor, cause the cam is snapping up the slack.

 

try removing the bolts from the distrubutor, and turn it past the holes. if it runs better one way or the other, maybe you are a tooth off.

 

with this, you van pop the cap, lift up the disty, and turn the rotor one tooth each way, if it is off.

Yes - I did have noise actually - was a weird vibration/buzzing noise - accompanied by a big tach jump (7,000 at idle...), but it was a ND disty, and the noise came and went. I have never heard a Hitachi do that. And I have seen hitachi's with incredible amounts of wear on the shaft, still running along as if nothing had happened (with slight tach jump sometimes).

 

Now your's is an EA82T, so your's could very well make different noises, etc. Especially since mine was on an EA81. It makes no difference tho - you can rebuild it just the same. Is there any play in the shaft? Any noticeable wear on the disty drive gear?

miles - The car runs fine. it has made this same noise for the 12000 miles I have had it put together. nothing new just noticed it changed tone when I loosened the dist. bolts.

 

GD - when the motor was apart the disty was ok. spun good with minimal play in the shaft. If you ever heard a toyota on nissan truck with a worn out timing chain its a little like that.

I am familiar with that noise.. my 87 Twagon disty made a noise like that.. I never remembered it doing that before the motor was out either... shortly thereafter, the ignition module in the dist died(probably unrelated) and I pulled it out and stuck my 88 disty in there.. noise gone..

 

BTW any EA82 CAS disty will work.. it doesn't have to be from a turbo.. 87 has a different wiring pigtail than the 88 and up, but they just unplug from the disty.. total swap time on mine, with wiring change was about 10 minutes.

ok so I hit the JY today. first i looked at a 92 loyal and saw the differenrt connector. then a 87 xt looked real similar to mine but it did not feel smooth. so i found a 87 turbo wagon A/T. It spins good and has the same conector but the cap is the type with the clips like a VW. I have not had time to install it yet. I will try this weekend.

 

They all had some little differances (part #as well) is the advance the same on all ea82 motors?

The different connectors can easily be changed.. only takes a couple of minutes.. Not sure about the advance, but I am guessing through use of different distys that they are all the same. In my experience, the 87 uses the clips, and the 88 and up uses the screw on type cap.
