Ok since the tune session at T1 back at the end of November I have driven the car three times. Each drive is a straight shot to show a friend then turn around and back home. The last time being the third the car threw the belts again, but this time within three blocks of the house the car started to blow smoke when I gave any gas. Since I was close to home I babied it and parked it. Today I final got to looking at things and working on the fender gaps and started it up with zero issues or smoke. The car ran for awhile and sat at operating temp then out of no where it started to blow white smoke. I know that white is usually the tell tell sign of coolant which is usually a head gasket issue. So I shut the car down and looked around and pulled the dipstick to make sure there was no white foamy residue or anything and there was not. After a few minutes I started the car again and it was fine then after 10 minutes of so white smoke again but this time I just let the car idle for a little bit and then within 5 to 10 minutes the smoke stopped. At no time the entire day did the car idle weird or chug like a train (usually a blown head gasket). The engine was rebuilt from top to bottom using OEM Honda and high end parts. The head gasket is OEM Honda and was brand new. Any thoughts or suggestions to this? I know pulling the head will let me know for sure but I'm trying to avoid that if possible.

 

Compression, blowdown, and block testers should all be in your near future.

The only thing that comes to mind is turbo seals.

 

Give more details about this^. What specific belts and why do you think this is happening?

White smoke can also be caused by water condensation in the exhaust on cold days. Is this possibly the explanation?

 

The belts are stock replacements and they are coming off with what I am thinking is due to the higher rpms and faster rpms the car is reaching. Does that make any since? The belts it has thrown are all three A/C, P/S and Alt. The weather outside is pretty cool but the first time it did this was on a fairly warm day with today being the coolest day it has run thus far. Turbo is brand new and I checked the pipes today to see if there was any oil in the lines and they were as clean the day I put them on. I need to check the oil feed line to make sure that I placed the oil restrictor on it. The turbo is a Bullseye / Borg Warner S256 that I purchased from Greg at Go-Autoworks. If that oil piece wasn't installed could this cause an issue? If it did wouldnt it have done it on the dyno? I do need to check the lashing on the valves to make sure everything is good since I haven't had a chance too since it was installed before the tune. The one thing that gets me is the car runs smooth as can be with no random hickups or erratic idle. I appreciate everyones help. This could not have come at a worse time because this weekend we were going to paint the car.

 

If you don't have a restrictor, that could blow your oil seals. Turbos weren't meant to handle the pressure your oil feed line puts out. Even at high RPMs, you shouldn't be throwing belts. Make sure their tension is within spec.

 

Yeah the belt thing is confusing me. It never threw one while on the dyno but when it hits the street and I get on it, it seems to do it. As for the oil restrictor I searched everywhere checking if that turbo needs one and I found a few places that says Borg Warner turbos have a built in restrictor. Im baffled at this point so I'm gonna go grab a pressure tester this morning and go from there.

 

Do the alt, PS, and A/C pulleys all turn freely by hand? Do any of the belts snap or show unusual wear or damage? Are all the pulleys from the components properly aligned with the crank pulley?

 

All belts turn freely by hand. Zero resistance and none of them show any unusual wear and tear. I have also checked to make sure they are all aligned properly which they are. I went ahead and checked the valves and all are good except cylinder 1 which the valves on both sides are moving so I am thinking its possibly due to the valve lashing.

 

The one spot I showed with a little white on it is the only area that I found it.

 

This new thread sounds familiar and possibly relevant.

 

Well I figured out why the guys at T1 said the turbo sounded like it was leaking exhaust!! The entire back was pushed way out as you can see.

 

thank you for that thread

 

Did the compression test and 141,142,142,143 so all is good there. Swapped the gasket for a new one and after running for about 10 minutes white smoke everywhere again. Please help Next thoughts are to yank the head

 

This just clicked in my head. Every time the car runs for roughly 10-15 minutes then the smoke starts. Its taking the car roughly 10-15 minutes sitting with cool weather outside to finally get up to temp and the clicking noise I am hearing is probably the thermostat opening and once it reaches temp the white smoke begins!!! Any thoughts? I think I am on to something aand most likely a band head gasket??? Thoughts please

 

When the engine was built, did you deck the head, was it straight? Def could be a headgasket issue, since oyu are seeing when the car is warmed up. I am wondering if the bad head gasket is raises compression at temp and causing your belts to run off.
