Hey everyone, so long story short I have 2 - 2003 Saab 93 Arcs. My saab I have owned for a few years so i know a little bit more about its history, unfortunatly I wrecked it. My second saab I bought it not to long ago off of craigslist when I bought it they told me that the engine in it was bad...

So, my engine suffered from low oil pressure and the bearings in the engine was replaced along with a connecting rod, crankshaft, and piston rings. Ever since I have had a loss in power, so I thought I'd do a compression test. The test showed about 115 psi on all cylinders. Next up I thought I'd...

Hi all, My 2008 9-3 has 145k km on it, and was having some cold start issues these past few weeks when it dropped below freezing at night. It would take a few seconds to catch, but once it warmed up it was fine. Yesterday morning was the first time it would not start at all...the starter motor...

My 2005 9-3 linear won't start. When it first failed, there was no fuel pressure. After the fuel pump/filter were replaced, still wouldn't start and it was discovered the timing chain had stretched and jumped a couple links. Following are the repairs that have been made and some current...

Hi, I'm needing to replace the head on my 1999 9-3 T5. (leaky valves, too many bodged exhaust studs) I have an excellent head from a B204, which I know the history of, but has a scrape on the surface, so will need a skim (again). So, I'm looking at ways to reduce the compression ratio back...

Hello everyone, I have a 1997 900SE 2.0L Turbo, with right under 150,000 miles. I just did a compression test and the results are as followed: Cylinder 1 180, 2 167, 3 170, and 4 180. This was done dry(no oil) with throttle wide open. AND Cylinder 1 240, 2 210, 3 224, and 4 228. This was...

I had the Cylinder head machined, put everything back together, and the compression on the cold engine is only at 120 psi (8 bar) across all 4 cylinders, when the book says it should be at least 180 on a warm engine. Prior to dismantling, the head gasket was blown (not from overheating) and the...

hi i'm losing compression on number 2 cylinder just 40 pounds should be about 150 , its a 1999 v6 turbo 9-5 griffin , is it much of a job to take off the head at the front of the engine ?

Hello everyone i had a broken front spring on my vector sport 05 plate 77K and had them both replaced i would have thought this would have fixed this noise,my suspension sounds solid and rigid on the right hand side but horibble the left side I am right in thinking it should be solid my...

I thought that it might be worth starting a new topic following my previous one on "smoke at start up". I have a V6 (petrol) which smokes on start up. After checking the turbo and breathing, I finally took my own much spouted advice and did a compression check. Not good! There is at least a 4...

2003 9-5 Aero, bought with 166,000 miles on in July, it now has 178,000 on the clock, has an LPG conversion and has been running well, but using a lot of oil like 500ml per 1,000 miles. Seems high to me, so I'm changing oil and filter this afternoon and while I'm there decide to do a compression...

I am about to embark on changing my HG (loss of coolant and misfire at idle when hot) so i tested the compression and came up with the following 180psi 185psi 170psi 200psi I did this on a warm engine and throttle open and cranked the engine until the reading reached its max, it...

Done a compression test trying to eliminate long standing stumble. Cylinder one 1 and 4 vary by 20ish psi. Middle 2 are same and between 1 and 4. Average 175psi. (cold). Does this seem okay or is it time for leakdown test?

Autoblog Green are carrying a story about a French company called MCE reviving the variable compression engine, a concept first made real by Saab back in 2000. They pay plenty of tribute to Saab in the press release, too. <blockquote>In March 2000, Saab unveiled its Variable Compression...

Hello, I am getting new wossner pistons for my 9000 CSE 2.3 FPT (having a complete engine rebuild and upgrade) and the tuner has asked me which compression ratio I want to go for. I am ultimately looking at having the engine at a max of 400bhp and was wondering at which point do the Saab...

Hi, Did a compression test as part of an ongoing investigation into an uneven running problem. Already put in new plugs and substituted the DI. Just wondered if these are typical of a B234R? cylinder 1. 162psi 2. 155 3. 160 4. 165 The guage is a...

Hi everyone, Just wondered if anyone knows what kind of reading one should expect for a B234R? Tony

My car has real economy problems and is oozing oil from everywhere. I have borrowed a compression tester to rule out engine wear before I spend any more money on it. What readings can I expect? The car has 150k miles but and serviced regularly by myself

I'm coming close to hitting that point where I just surrender (to what, I do not know) as far as fixing my '82 Turbo goes. I've re-built the engine three times now. Upon finally assembling everything for the third time and trying to start it up again, I have experienced a third problem that may...

2001 2.2 TDI -Whats correct cylinder compression Hi , I'm fairly new here so did carry out a search prior to posting this but i couldnt find what i needed . I have 2.2 tid SE 2001 with 107,000 miles showing. I have been using some oil (no leak) which has got me a little concerned. There's...
