I changed out my PCV diaphragm, spring and cap with the Dorman part this morning. I first thought there was nothing wrong with the one that I removed but upon closer inspection it had a tear in the edge next to the thicker sealing ring of the diaphragm. I used a Popsicle stick inserted into the mid ...

New Diagnostic Development. I decided to walk back out to my car. I cranked it and it ran as normal without the noise. I then put my finger over the hole in the PCV diaphragm cap and the valve started making a slight horn sound at the valve a little like it did when I pulled the dipstick earlier ...

Thank you Paul. It only made a noise when I pulled the dipstick when running and shut up when I put the oil dipstick back in. I have the Dorman PCV membrane kit on the shelf because I know they fail often so I bought it during a time I found a deal on it for $14.90 on Manufacturer Rockauto close out ...

Thank you Paul. I did not realize the car would even run with the MAF disconnected. I will give this a test tomorrow. I did go out this afternoon and had the hood up, then cranked the car but seem to run normal with no odd air intake noise. Like most things, it would not do it when you want to test ...

I did replace the whole PVC unit with a Volvo part a few years back and the car is not driven much but I have not thought about pulling the dipstick since this noise was not the normal high-pitched PVC noise. Thank you for the suggestion I will pull the dipstick and see if it changes the next time I ...

OK, I have a head scratch-er of a problem with my 2008 XC70. No engine codes present. When you initial crank it after sitting for a while, the engine fires up sounds fine and then the sound changes almost like an intake that does not have a filter housing on it. A throaty air sound. Car has no power ...

Pull the oil stick to break the crankcase vacuum and see if the noise stops. If so, something went wrong with your diaphragm install in my opinion.

Today, My Son and I changed out my Radiator on my 2008 Volvo XC70 3.2 with 230K miles on the clock. A long time ago I had to change out the fan unit on this car and then I thought it was the worst engineered vehicles that I have ever worked on. Particularly also felt that way after doing the ...

I am curious what are your symptoms to make you think you have bad subframe bushings?

I have had a problem with my power lift gate latch for a long time on my XC70. You could not open the hatch from the outside using the handle. It would only open with the remote or button on the dash. Today I decided to pull the inside cover. I removed the latch and the side control box. I found the ...
