Question 92 Accord Ex Smoking issue Please Help!

I recently bought a 92 Accord with a F22B2 engine. Its all Stock. The head was fully rebuilt with oem honda parts. I noticed the other day when i got on it past 4000rpm it would smoke a little until i shift. The smoke is gone in seconds it looks blue like burning oil. But im not losing hardly any oil the engine is very strong. Doesnt seem to be losing compression or anthing. I did notice that i had a little oil in my spark plug chambers. could that be why its smoking at higher rpms?

My guess would be valve seals but if the head was fully rebuilt then I guess it could be piston rings are a little worn out. I would get it compression tested first and go from there.

Alright. I wasn't sure. Cause I know that oil is probably coming from the lower tube o rings into the spark plug chambers. I'll have a compression test done next. After I change those rings.

I would like to know also as mine does the same exact thing.

I've had mine compression checked at work and its 185 on all 4 cylinders.

I have no oil in the sparkplug tubes and no indication of oil in the piston chambers or on the end of plugs.

PCV valve is also clear, and no indication of oil in the IM anywhere.

Sorry OP for chiming in on your thread.

When mine smoked at that RPMs, it was due to busted ring lands. Drop the idea of a compression test, do a leak down test.

And oil CAN NOT leak from the spark plug tube into the cylinders..... Not unless your plugs are ridiculously loose.

to the op...its more than likely gonna be the seals on ur spark plug chamers u have to un bolt the lifter assembly using 12mm n 10mm sockets n flip it upside down n replace those seals it comes wit the enitire valve cover gasket set. n there is no need to take off the distributor or even loosen it n no need to even touch ur cam gear either

I already knew what to replace for the spark plugs chambers. I just wasnt sure if that could cause the oil to leak into the cylinder. But thanks for all the help guys! Im going to get a leak down test done soon. I feel that my rings are bad. Cause ive went through everything twice over and i cant find anything else for it to be. But I also have another question. When I pump gas and fill my tank when the pump clicks off I have gas leaking out by my passenger rear tire right above the exhaust. is there a seal there or something?

fleetw00d is very helpful fleetw00d is very helpful
The fuel fill pipe assmbly has vent line that runs parallel to the main pipe. If it only leaks when you fill it, this vent line may have a rust hole. Before you fill up next time, remove the wheel well liner behind the left rear wheel so you can see from where it is leaking.

He said he's leaking on the passenger side, not drivers side.

92 CB7 with a F22B2 stock? Also did you rebuild it or someone else? Sounds like valve seals to me.

It only leaks when I fill up. Its fine until the pump clicks itself off then i hear it splashing on the ground. I figured it was like a hole or a gasket between 2 pipes. Ima get under my car today for an oil change so ill inspect it a little more. It was rebuilt at J Mills Tuning shop. Which is a well known shop for its engine builds, swaps, and tuning Where i live. I purchased it from them it was fine when i bought it. the day i got it it didnt smoke. this kinda just started to happen about a week ago.

Sounds like valve stem seals. You can mask the problem with a heavier oil like shell rotellas.

Well then that must be the issue cause I've been using 20w-50 oil and it's doesn't smoke nor burn oil for a few days.

First, go back to 5W30 motor oil, if your 20W50 comment is true. I'm not sure if you were being sarcastic or not.

One person mentioned piston rings for the blue smoke out rear at higher RPM's. Take the person's advice and do a leakdown test.

Valve guide seals if blue smoke upon cold engine start-up.

Spark plug tube seal oil leak fix is in DIY section, that is an issue in itself.

As for fuel leak, I would say do a visual inspection on passenger-side fuel tank area. If it only leaks when near full, then obviously look towards top of tank area, perhaps there is corrosion involved.

No sarcasm I was told to use a thicker oil by a friend. I've already fix the fuel issue. I had a rust whole in a pipe close to the top of the tank. I emptied the tank and had it sand blasted and welded a new piece over the whole and smoothed it out and primed it. I also fixed he sparkplug chambers leak. But I know that when I use 10w40 it smokes so I mix one quart of 20w50 with 3 quarts of 10w40 and it doesn't smoke for a few days. When I changed my oil last it was really thin almost like water
