Spark plugs are getting oil fouled quite badly on the electrode end of the plug, the spark plug tubes have new seals and the top end of the plugs are clean as, but they are getting oil on them on the electrodes. Funny thing is my honda doesn't smoke at all unless its a really cold morning and compression seems ok but have not tested. What can i do to fix this! TIA H22a Honda

are all the plugs foulded or just paticular cylinders. How many kms and what year!

if they are all doing it then you could try going up 2 steps in the heat range. worked for me

All of the cylinders. 180,000km. Not sure of year as dont have car here. Think its a 92 or 93!

Some cylinders are worse than others but they all have it to some degree

Drive the car differently. Change the oil grade perhaps.

I would add some engine flush to the oil, then drain it, and use a different grade, say 15w40. Then, when the engine is warm, do a compression test and let us know the results. From memory, H22A engine uses NGK brand, BKR5E-11 spark plugs.

2 reasons for that . either your valvestem seals let loads of oil in the chamber or your oil control rings let the oil past on the piston. if it smokes after driving down hill then it valve stem and valve shafts possibile worn = head rebuild. other one is full engine rebuild or bin the engine or whole car.

use Bosch or Champion plugs instead of NGK.

No, don't!

um sorry but thats stupid advise oil on plug got nothing to do with the brand of plugs

please yourself - but have never liked NGK's anti fouling abilitties , real evident in single cylinder machines .

try some moreys upper cylinder lube

I found the opposite, I like NGK.

I always use NGK. Dam good spark plugs.

I will give that a try. Been meaning to buy a new tester for ages my old one got broken. Any recommendations for a good compression tester that won't cost me a fortune!

As morrisman said, go to a hotter plug, only I would try just 1 step first rather than 2. Engine with that amount of K's will be letting a bit of oil past the rings so a hotter plug will help burn it away. Also if you are running 91 you could try running 95 or 98 and see if that helps.

Al my life i have heard really bad things about hondas, from mates to mechanics i dont even know. Why are hondas so bad! is it just inferior engineering or people jumping on a bandwagon!

you have not heard about mitsubishis then have you!

lol them too. good thing toyotas and nissans are keeping us afloat
I am wondering if you are still getting oil into the plug tubes and are getting it on the electrodes on the way out.
Take a plug out and shine a light down there and have a good look.

Motors smoke less than "in the old days". Its a bit like looking for a "Grey" tail pipe. no lead in petrol these days, so no grey. Top part of motor - rocker cover, cam area , which at one stage would show fumes , now has tube fitted from there back into the inlet side , so these fumes get re-combusted. Jap engineering :usualy by the time smoking is plainly visible is getting ready to go "bang". Try a compression test. If nothing else it will eliminate some options.

You were misinformed then. I've had an old Civic, two Accords, one Orthia, and still have the Odyssey. The only issues I've had was maintenance items.

Definitely oil fouled not fuel fouled. A mate said that also, i may just replace pcv valve as they are cheap as anyway. cheers
