New Volvo Owner/Project

Ok, the smoke went away! It must of had a lot of water/oil in the engine or exhaust as it took a while to burn off.

I will re-time the VVT this weekend when I have more time. I'm also planning on replacing the thermostat because it's still having trouble keeping warm.


The only other thing I noticed is a light and random transmission clunk when sitting at a stop light in drive with the brake depressed. Is this normal? It didn't seem to do it while in manual mode. The transmission is butter-smooth otherwise. Shifts are very smooth.

Replace your thermostat to cure that cold running problem. That will also help mileage and drive ability

It can take quite a while to burn off residual moisture after engine work.

Your. 2001 has the notorious Stop-neutral transmission software that you should have removed at your Volvo dealer. If it is shifting ok but just bumping at stop, that's good.

Thank you abscate,

I replaced the thermostat, and that cured the temperature problem.

I re-timed the VVT. I thought it was good, let it idle min after (with occasional revving) and no check engine light, so I took it for a short test drive. Everything seemed fine. I started the car the next day and the P0014 code came up immediately. Not sure why It didn't come up last time? I have a OBDII "ultragauge" that monitors the OBD system at all times and will beep when I get a pending code - a code that hasn't yet illuminated the check engine light.

I tore it apart (again) and this time completely removed the VVT pulley and re-timed it from scratch. Got it back together and let the car idle for a little while to make sure I wasn't going to get a pending code. It was clear, so I took it on a test drive. This time, the car had a noticeable power gain from before. It was running smooth and strong, and I was feeling good about the new VVT setting. (the P0014 code hasn't come back).

I was almost done with the test drive when I felt a very sudden loss of power, I immediately got a pending check engine light. It was so dramatic and sudden that it almost scared me. It continued to run (although rough) and I drove it back home. I checked the code and it was P1238. Turbo related. I took a quick look and realized the high pressure hose going from the turbo to the intercooler was disconnected where it meets the soft rubber piece on the radiator side. I must have not tightened it enough and it "poped" off. I reconnected the hose and started the engine. All was smooth!

While at idle, I cleared the code. As soon as I pressed the "clear code" on my OBD scanner, the car died. I tried to re-start the car and It would start up, run smooth for 1-2 seconds, then sputter and die. If I rev the car when it first starts I can keep it running, but it wants to die if the revs get below 2K. I thought the computer might be trying to compensate for the massive air leak and was confused when I cleared the code, So I disconnected the battery to reset the computer, but the problem is still here. I let the car sit overnight and tried again, but no luck. Still starts up, runs for a second or two, then dies. I don't know what to do? No check engine codes are present?

More turbo leaks. Check the entire induction path and do a visual on the intercooler , best you can. They can blow out, but it's much more likely a hose that has popped after the turbo.

[abj1]

abscate, you were right! Thank you!

Somewhow the hose from the intercooler to the throttle body blew off the throttle body. Strange, I'm not sure how I managed to blow both hoses off at the same time? I tightened the hose clamps no different from other hose clamps, but you must have to really crank down on the turbo hoses.

Thanks again.

That no-idle condition is classic for popped induction.

Well done!

Ok, I have another question. I'm still not able to get rid of this stubborn P0014 code.

I have a home-made cam holding tool. It works great. I have used three different techniques now to set the VVT and have got the same P0014 code every time.

The three different techniques I've tired are:

1.Use marks to keep track of where/how VVT was installed originally (try to keep same as before) Result = P0014
2. Use this method: viewtopic.php?f=11&t=35478 Result = P0014
3 Use this method: Post #6 http://volvoforums.com/forum/general-vo ... c90-32431/ Result = P0014



I'm confused why I'm not able to get rid of the code. My thoughts are:

1. My cam holding tool holds the camshafts in-line with the cylinder head. Does the official tool not keep them exactly parallel? Or is one cam tilted slightly from "straight"? If so, that could be my problem.

2. I have another issue altogether. (cam sensor, VVT solenoid, etc...)

I'm starting to get frustrated. I'm not sure what I'm doing wrong.

Isn't P0014 air mass fault of some kind? Google that one and research it

[abj1]

P0014 = “‘B’ camshaft position - Timing over-advanced or System Performance.”

[abscate]

I confused it with P0114

Your are slipping a tooth when you install. I think this covered in a recent write up I will try look for.
