Hi All,

My son picked up his first car recently, a 1991 Honda Accord EX-R that needed and needs a lot of work.

1) Drivers door latch-now fixed
2) Muffler & tailpipe assembly-now fixed
3) Heater fan blower motor-replaced but very little air comes out the vents or defrosts. I’ll have to go back in and see what I did wrong.

He took the car to work for its maiden voyage yesterday and when he got home there was a miss in the number three cylinder. I pulled the lead wires off each cylinder while the engine was idling and the 3rd cylinder is the only one that didn’t make a difference.

I removed all 4 plugs expecting to see the #3 wet and fouled but it looked just like the others, dry as if it was firing. I did a “hot engine” compression test and all 4 cylinders are at 190 psi.

I’m wondering if anyone can tell me why the plug in the #3 cylinder would not be wet if it wasn’t fireing?

Thanks for any and all feedback!

 

Never mind, I think I located the problem with the # 3 cylinder miss. I pulled off the distributer cap and found a large pool of motor oil sitting at the bottom shorting out the #3 rotor cap contact. Now I’m wondering how the oil got into the distributor cap? I will do a quick site search and see if others have had this issue in the past. Thanks.

 

Probably have to replace the distributor o-ring.

 

If there is oil inside the distributor it will be the inner seal not the outer o-ring that is the issue. This seal can be replaced, however there is no Honda part number. You will probably have to buy it from a seal or bearing parts store or from an online source. The part number is NOK BH3888E.

There is a pretty good DIY here on H-T. If you do a search for distributor inner seal it should come up.

 

Ya, I found out there is no Honda part number by calling the dealer an hour or two ago. I did manage to locate the DYI so will get the parts ordered on line and get at it in a week or two. Thanks for the info!

 

Sounds like the problem i came here for. My 1990 has a slight miss, but only at idle. I did the same process with the plugs and nothing. I suppose I can start with the distributor.

 

Yes, look under the cap and if you find oil pooled up near the #3 rotor contact...

 

When i did this while back, I couldnt find the right seal so i used some gasket maker.
worked good for about 3 years then i sold it, dont know afterwards.

 

I ordered the seal and O-ring kit off eBay late last night and got conformation that it shipped this morning. Total for both pieces including 9 bucks for shipping to Western Canada was $18.93 US.
