Alright guy I asked for opinions before but now I need help, I cannot figure this out. I have a built LsV that's running great but it keeps smoking dark grey to light grey smoke, I changed piston rings, valve seals, head gaskets. I checked valves, and exhaust. And everything is good. Idk why it keeps smoking. People tell me it's the type of gas I am use and the type of oil and stuff like that, but I want to ask the experts before I start changing things. Let me know what it could be. Thanks

 

stuck pcv valve or its burning oil or trans fluid.

 

Burning trans fluid? Lol, expert analysis above.

One thing is for certain, you will never see a stuck pcv be the root of a smoking problem on b-series. It's wishful thinking.

If you have to change all these parts in the engine and have not successfully diagnosed the issue, then it sounds like you need to bring the car to someone who know what's going on.

 

Sarcasm?

 

No! how the hell do you burn trans fluid out the exhaust! ??? SMH some people i tell ya..


Do a compression test and leak down test.

Its not the type of gas or oil used, your experiencing blow by.

Does the engine smoke at idle or on decel? and or WOT?

Could be valve seals and or piston rings. If you just rebuilt the motor its possible either the rings were not installed properly or the engine was not properly broken in and you have blow by.

Or your lsvtec conversion is leaking oil somewhere in the engine. I believe theres a oil galley that needs to be tapped with a allen bolt and if its not done you will have oil burning in the engine just an idea..

Now, we need to begin with the head installation. Make sure you have already installed the oil galley plug into the head and that it sits flush, this is imperative to redirect the oil flow via the external oil lines to activate vtec. Alot of people complain about oil leaks with lsvtec setups. You ask them if they installed this plug and they ask you "what is that"?.....just turn around and walk away. Ok, now the very first thing you need to do is set the block to TDC. This means setting the 1 and 4 pistons to the very top of their stroke. This will aid in the ease of the installation of the timing belt later. You can do this by putting on the crank pulley bolt and tightening it on enough so that when you rotate the crank counter clockwise, it will not come loose. Always rotate the crank counter clockwise. The motor does not naturally spin clockwise, so do not force it to spin that way. Now, there is a mark on the crank gear as well as an arrow on the oil pump. Align the crank gear to this small arrow above the gear and you will notice that the motor becomes set to TDC when the marks are aligned. Now for the head installation...begin by sliding the LS/CRV (90-01 LS or 96-00 CRV, whichever block you have) head gasket over the head studs onto the block. Now install the dowel pins into the exhaust side of the head (for lsvtec motors). Slide the head over the head studs until it rests flush on the block. Make sure the dowel pins line up as this is critical. If the head needs a little persuasion, tap it with a rubber mallet. Next, slide on the ARP washers and nuts. Torque them down to ARP's recommendation (65 ft/lbs on GSR/ITR studs, which is what you use for lsvtec's), not honda's, using the ARP moly lube. But, follow honda's recommended torque sequence:

 

He never specified the smoke was coming from the exhaust... smh, some people...

 

lol yea ok cause when someones engine smokes no one should rule out the trans smoking cause that happens often.

Transmissions don't smoke buddy!

Maybe if coolant spilled then it would slightly burn off but not smoke, thats generally related to the engine blowing a white smoke out the exhaust/tail pipe usually related to coolant burning inside the engine or oil burning from blow by.

 

So you say it's smoking from the exhaust, which the op never stated, then you specify the engine, again which the op never specified. It was a general gray smoke inquiry. Are you that inexperienced you've never heard of or seen trans fluid burn, OR a trans smoke? Although more common in automatics, it does happen in manuals often enough that I mentioned it when the op asked for some assistance. So get your mightier than thou head out of your *** and take the ops question exactly as stated. Make recommendations from there. While I do agree with your "things to look at", to discredit mine makes you look like you're just regurgitating something else you've read in a forum.

To the OP, there are a few suggestions here to look at. They should get you close to the resolution.

 

Thank you guys for everything I figured out the problem and you were right it was a blow by this is the second time this guy helped me change my rings and it cracked again and pop off cause he didn't install it correctly. Thank you so much for your guys help. Really appreciate it.

 

I would of never thought it could of been a blow by. Thank you again

 

Im not saying im a expert but in my 9+ experience with hondas B series in specific, I have seen this many times as well as experienced it myself. And when someone states there smoking and they "just changed rings valve seals ect ect..) its obvious there refering to "smoking out the exhaust" when they say " its smoking!" cause blow by is usually always related to that.

I understand what your saying as far as it could be smoking as far as fluid burning off but i have never seen a trans leak and smoke from burning off on the case im sure its happened but i just never heard of it happen in a honda. And it is a good assumption for coolant leaks can cause grey smoke in the engine bay but again the op to me made it sound like hes refering to the engine smoking out the exhaust not smoking from the engine bay ect ect.

 

When someone says their car is smoking, they mean it's coming out the exhaust because that's where smoke comes from 99% of the time. We assume this because it's the norm, this is basic English language stuff. If they specify otherwise, then we can speculate about the other possibilities.

And no, transmissions don't usually smoke, if yours does, perhaps you should stop riding the clutch so much.

 

Issues been resolved. Why are you here? To run your mouth and look for attention? That's exactly what it looks like.
