Car Fix DIY Videos

Welcome to the Channel! In today’s episode I show you how the intake valves on the 2007-2011 Saab 9-3 with 2.0 and 2011 Saab 9-5 can wear making the engine lose compression. I also show you how to compression test the engine and talk about how to fix the issue. This is a common issue with 2007-2009 Saab 9-3 2.0 more than any other years, and there is a TSB from Saab that goes with it that does include the 2010-2011 9-3 as well as the 2011 9-5. The TSB is below.

TSB:
Title: RE-ISSUE: Hard Starting Cold With Engine Misfire and Low Compression, Vehicle Starts and Runs Normally When Hot 2007-11 9-3 B207 & 2011 9-5 A20NFT

Date: 12/17/2013
To: All Saab OSC’s/WSP’s
From: SPNA Technical Assistance
______________________________________________

MODELS:
2007-2008 Saab 9-3 B207R (This PI does not apply to the B284 engine)
UPDATE: This condition could also occur on 2009-11 B207 or 2011 9-5 A20NFT
CONDITION/CONCERN:
A Technician may comment of hard or no starting when cold. They may also find engine misfires with DTC’s P0300, P0301, P0302, p0303 or p0304. The vehicle will start and run normally when hot.
RECOMMENDATIONS/INSTRUCTIONS:
This condition may be caused by a worn intake valve and is typically found on vehicles with 50,000 or more miles. Due to the nature of this issue it can be more frequent in cold climates and could exhibit the condition at a lower mileage; inversely in warmer climates it may occur at a higher mileage.
TAC has found intake valve wear of the valve seat face will cause significant compression loss in cold temperatures that will not be readily apparent when hot.
To properly diagnose this condition perform a cold (after an overnight stay is best) compression and leak down test. As an example, an engine with a 150-175 psi hot cranking compression reading may only show 75 to 90 psi when cold.
Once a Technician has determined he has the above described concern he must initiate a Technical Assistance Center (TAC) case by email at xxxx or by phone at xxxxx prompt #3. TAC will provide the full information on the parts/repair procedure when the case is set.
Parts Required: Inlet valve 2007 to 2011, BioPower 55563529 (8 required)

To do the compression test you will need:
Spark Plug Socket w/Extension
10mm Socket (to remove coil packs)
T30 Torx (to remove coil pack cover)
Compression Tester (I used a Bosch Unit that I can’t find the PN for — find one similar at your local parts store)
Needle Nose Pliers (to remove Fuse #2 in front of the battery box — Fuel Pump fuse)

I’ve fixed this issue by removing the head from a 2008 9-3 2.0 and replacing it with a 2003 9-3 2.0 (Sedan not Convertible) head that I had completely machined and went through at a local shop. You MUST use the cams from your car, not that come with the replacement head if you go this route.

Looking at just replacing the valves like the TSB says? here’s a link to the recommended valves.

Looking at doing the job yourself. Use WIS! (and get the right cam locks)
