There are actually two types of single-row IMS bearings. The smaller one (up to 2005) and the larger one after that, which exhibits a much lower failure rate, but can only be replaced by splitting the crankcase. The IMS was eliminated with the move to the DFI engines.
Had Paul work on my 986 really knowledgeable guy, replaced my front suspension and went all over the car to tell me things I needed to keep an eye on, great guy took photos of all the work he did and kept me up to date with progress.
Yeah, he's a legend.
But did you clean the engine before putting back the clutch? It was so dirty 😂
The two things that increased the enjoyment of my 2000 Boxster, replaced the 10 year old tyres and put back in the stock exhaust. Those low profile tyres have to be fairly fresh or you feel every bump in the road because the side walls no longer provide much flex, and as to the exhaust the after market exhaust had a horrible drone at highway speeds. Still, I would like to get one with the PDK. Thanks for posting.
Just found your channel! I had a 2007 boxster with the 2.7 engine. You explain things really well. Mine was pretty good only manifold bolts and gasket done and hood elastic. Fantastic to drive and may have another. Annoying thing is wheel bolts going rusty!
I believe my 986 had a double race IMS bearing which didn't fail. I had a new one put in anyway at 120,000 kms to be on the safe side, when the clutch was replaced. The 987 had a single race and that had problems but mainly in the USA where oil quality and so on is not quite the EU standard. I also changed the oil and filter ( when in Queensland ) every 4000 kms. Great insurance for only a few dollars.
Excelleeeeeent vid..
When a Neil asks for help to fix a potential problem...its a good thing....

Thanks for sparing us the endless sped up footage of men undoing bolts that most car vids include.
No problem 👍
The EPS bearing actually uses roller bearings (cylindrical) rather than ball bearings. There is endless debate on the benefits and disadvantages of both types. In the end it comes down to personal choice and location inho. US seems heavily biased toward LN ceramic bearing while UK seems more open to EPS
Oh man it looks soooo much easier removing a gearbox up on a lift.. Just spent a full day doing a clutch on my BMW in my driveway!
Watched that earlier - looked a real tough one; especially the refit. Great job mind.
Hey George, saw the video. Top work. Quite an effort that. I wouldn’t have attempted it on my drive!
Great and informative video. I would have liked a longer version though.
Noted!
Somehow I managed to drop the gearbox in a single garage using a jack.
I had the same intention of replacing the IMS but was greeted with a leaking butched cover plate covered grind marks!
Sadly I lost all faith in the car at that point, so popped a new clutch/flywheel in, replaced the RMS and sold it on.
I presume on the 987 engine you don't need to lock the camshafts.
i have an early 2005 boxster, thanks for this video!
I like these maintain-it-yourself vids. Would be useful if you could put a timer on the video to give some idea of the realtime it takes to complete these jobs. Other than that - good job!
That's a good idea. This job took 9 hours but obvioulsy next time it'd be quicker as I now know what I'm doing.
I'd have placed the gearbox on the floor asap. Good job though...oil leaks from my 986 was the actual IMS cover not the RMS but I replaced both as well as a new IMS bearing , clutch , flywheel , clutch slave etc etc.
Yeah, it’s safer but it’s soooo heavy! Surprisingly the stand holds it quite securely. Good stuff doing all that work yourself. Are you a mechanic by trade?
I’ve got a really strong steel table on wheels that I always put under the car for placing tools mostly but just in case the lift fails. Won’t happen but…
Trout farmer actually but have to service all my work vehicles and machines so fairly proficient, currently working on my 996 Turbo brakes (new calliper seals etc)
Good luck with the Boxster
No locking of camshaft ???😬
It's recommended but time consuming. Most people I spoke to don't bother. I guess we'll see when I start the car....
If you had that bearing & clutch replaced at a Porsche dealership, I reckon it would be a £3k-ish invoice!!
At the VERY least ! With a high mileage vehicle around 20 years old, you can be fairly sure that other parts and jobs will need attention with either the transmission or engine out of the chassis. Rusty brake lines and corroded up aircon pipe terminals spring to mind. Try to always budget for extra costs !
Now the IMS is fixed, is the next job bore scoring? I’ve owned 5 Boxsters over the years starting with the 986 onto the 987. Absolutely loved them them but no more. The bore scoring issue is always there in the background for any high mileage Boxster.
From my research bore score is due to the forged pistons in the 3.4l and larger engines. The 3.2l and below use cast pistons that don’t expand under heat so no scoring.
Wasn't the problem with the IMS down to it being sealed and not being lubricated by the engine oil ? I thought 'the fix' was a kit that comprised an oil way into this... or am I going mad ?
There is an option of a kit that has an oil feed to the bearing. I believe the main problems with the single row bearing were it being not able to take the loads and/or grit getting into the bearing during manufacturing that causes wear.
@@RoadandRacetv I thought the reason for failure was lack of, or poor, lubrication causing overheating and failure. From an engineering perspective, spec-ing that type of [sealed] bearing in a such a location isn't a good idea at all.
Nice video, could you tell me how/ where you supported the engine with the gearbox removed?
Thanks Jimbob. It’s supported just where the gearbox meets the engine. There’s a flat surface. If you look at my previous video I show exactly where.
You guys didn’t lock the cams 😅
what was the mileage on your Boxster when you pulled the IMS?
80,000
@@RoadandRacetv Thanks and the IMS single row still looked good!
What year did they move away from the fried egg head lights?
2005
Late in 2004 (2005 model year)
@@simoncrest5354 Thank you.

What is a Porsce Boxster?😂😂😂😂
How embarrassing....
All good mate! Enjoy your videos!!
