My b16 is only running on 3 cylinders and it has good compression on all four cylinders and good spark. The car floods out the plugs after driving for about 15 minutes. It also emits alot of white smoke which does'nt go way after warming up. I do not smell antifreeze either. Also when you pull the vacuum line off the FPR it does'nt send my fuel pressure higher. I have replaced the FPR and put a new new head gasket on it and shaved the head and done a compression test on the head which checks out fine. The valve clearance is Ok on all the valves also. What can be wrong?? I didnt put a new intake gasket on it because I had a reusable Hondata gasket. Maybe this is my problem. Any ideas??

 

Your problem isn't the intake manifold gasket. That would cause a vac leak at worst.

So what makes you think you're running on three cylinders if you're getting spark, fuel and compression across the board?

 

Stuck injector? do a leak down test just to confirm that everything is in good shape.

 

White smoke=Water.

 

When I pull the spark plug wires off the first 3 cyl each time my engine bogs down but when i pull the 4th wire off the engine does nothing. After driving for about 15-20 minutes and you turn the car off it will barely start and when you check the plugs the first 3 are wet and the 4th one looks brand new. I had my injectors sonic cleaned also.

 

swap the injectors around and try again

 

I have tried switching injectors around and it didnt help.

 

It still does this on the same cylinder? When you pulled the plugs did you pull them one by one? If you stand infron of the engine looking down the cylinder order is 4321
which cylinder is not working?

 

Yep I pulled the plug wires off separately one at a time. standing in front of the car from left to right with the plug order 4 3 2 1. with 4 on the passenger side and 1 one the drivers side. Plugs 1-3 bog the engine down when the wires are indvidually pulled and they are wet. But plug number 4 when wire pulled off does not faze the engine at all. And the plug when you pull it out it still looks brand new. Not wet its dry as a bone looks like it was just took out of the box.

 

okay so no feul on 4. Switch an injector from 1 and see if it gets wet. if it does not change then you either have a bad injector clip on #4 or there is a break in the #4 injector wiring.

 

or dead cylinder

 

he has good compression in all 4 holes.

 

i switched out injectors and no difference. i checked to see if the number 4 injector was getting power and it is. I have 155-160 lbs compression on cyl 1-3 and 138 on cyl 4.

 

Im gna do a leak down test tomorrow.

 

Those numbers are low for a b16. try putting a teaspoon of oil in the cylinder with the lowest Compression reading and do it again. I bet it will shoot up to 190-215.

I think your rings are toast... Or bent valves

 

might have a faulty spark plug wire as well...switch plug wire 3 and 4 and see if it's still happening...!!!

 

Im also gona redo the compression test i was in a hurry (my wife was rushing me) and I didnt check it WOT.

 

I just put new honda OEM rings in it and had the block walls cleaned up when I had the head serviced.

 

All 4 of my wires have strong spark I have a MSD setup on it. I switched the wires and it still has the same strong spark on all four.

 

Up date?

 

ok, also.. just wanna put my 2 cents in also.. and this is very possible and fairly common even for the most experienced mech. you may have aligned the piston rings on that once piston all the same way with the gap of 2 or more rings on the same side. that is a very common problem. also, beansandrice right about that compression.. that is very low. im sure you dont need to run WOT on compression tests. just pull the injector plugs and turn the engine about 8 revolutions, or 8 seconds if im not mistaken

 

Correct! I are the rings clocked?

 

Yep most of my probs were pretty simple. The reason my fpr wasnt reacting when I pulled off the vac line was the fpr cutoff solenoid valve was stopped up. And the cyl #4 when I originally checked the power wire going to it with a cheap light tester it lite up. But when I hooked up a continuity tester it barely had a reading. I traced the whole line down and it had a break in the wire holding one by one strand. I fixed the wire and it work like it should. all 4 cylinders firing. It runs awesome. But it still has alot of steam coming out of the exhaust. I installed each ring on the pistons in opp directions to make sure I wouldnt have problems. My engine has about 80k miles on it and the machine shop told me the block was in great shape it looked barely worn and miked out the same. So he just lightly honed it out and told me to order stock rings. So I did and we installed the rings together. But Im using an old set of comp gauges here at my shop at the house. And I redone the comp test this morning WOT and they were between 155-170. But when I added a couple teaspoonfuls of oil they shot up to 235-250lbs which to me is odd. My b16 service manual says the compression should be at the lowest 135 and new it was 185. But someone here locally asked me if I have replaced the cat converter/resonator lately and I havent its been on this car for 100k miles(before the b16 install). He said it could have alot of buildup in it causing the steam.

 

The resonator or cat converter some call it has about 20k miles on stock motor and about 40k on the b16. When I did the comp test I did disconnect the fuel pump and disconnect the dizzy also and remove all plugs. Maybe I should borrow a newer gauge from another shop to see how it reads. Because the 250lbs of comp still sounds way to high and the 155 is a little low with new rings.

 

your compression is well between specs and under the maximum amount of variation (28psi, yours is 15).

If the smoke billowing out the back of the car is white, i would be looking at any possible coolant loss. If there isn't any, and you're not losing oil, it's perhaps just condensation in the exhaust system?
