1998 V70 T5 with 160,000 miles. I've had a recent oil leak, very bad and seeming to get worse, and finally got around to installing the oil separator box kit from IPD (great kit with Volvo parts) which was suggested as a first step before doing the rear main seal. I followed the instructions from Matthew's volvo site to do the job. Instructions were excellent and a big help. However, I found no clogs and did not have the telltale puffs of smoke from the dip stick. PCV valve was not clogged either. But all of the hoses were rotted, or broken or brittle, so I am glad I did it.

I checked the rear cam seal on the exhaust side and discovered the seal had been blown out of the block, it was just sitting there. I suspected that the huge amout of oil the car was dropping was coming from the dislodged seal on the rear cam seal housing. I replaced both rear seals and used volvo seals from the dealer. I also pulled out the abs module while I was at it because it is going bad. I replaced as much vaccum line as I could find, cleaned everything up, pressure washed the engine, top and bottom. Changed the oil and filter. Put everything back together, had no "extra" parts, all seemed good.

I then tried to start the car. It fired up, and then died. It won't idle unless I am running it at 1000 rpm. I have no power assist with the braking, unless I am in neutral, racing the engine, then I have power assisted brakes.

If I come to a stop, the engine will die. At first, the car ran very strong, really impressed, even though it would not idle, but at the end of the test drive, I was hearing back fires and the power had dropped off noticeably on hard acceleration.

I know it is ridiculous to ask "what's wrong" in the abstract, but I was hoping that the fact that I don't have power assist on the brakes might give some clue to what I may have done wrong. Just coasting to a stop with the car in gear, I really have to stand hard on the brakes to get the car to slow down. If I have the car in neutral, racing the engine as I come to a stop, I have power assisted braking. I don't think removing the abs module affects the power assisted brakes, only the abs. I don't recall removing any brake vaccum boost tubing to do the job. I checked all the turbo hoses and made sure they were all very tight and not blown off and they were all secure.

I am thinking that I have an open line somewhere for the power brake booster, but I don't know where to look to find it.

Any suggestions would be appreciated.

Thanks.

P.S. I just checked under the car and there are some new oil drips too!
