2003 Porsche 996 Carrera 4S

PostPosted: Sat Feb 09, 2019 5:14 pm    Post subject: IMS oil leak + oil cooler leak. Reply with quote

Hi,

I removed gearbox with some problems as Porsche Dealer Parts Department representative point put "not unusual stuff" and find all my Pork sweats - oil and coolant leaks.

IMS flange is leaking a lot I need to take it out to do this I have to lock cams where I can find exact dimensions of that super complicated tool so I can manufactured myself....?

I will end up installing new bearing but do I have to take it out before order just to be sure what bearing I need or can I just go and buy new one?

Also what I can see there is coolant leak between oil cooler "heat exchanger" and engine I'm guessing seals are gone could be oil cooler leaking too... Porsche Bolton quote me £198.66+VAT for oil cooler and £4.88 +VAT O-rings, carparts4less got in offer Hella for £111.79 not sure if this will came with o-rings.

What I would like to ask will be an easy job to take it out without lowering engine since gearbox is out? do I need to remove any other parts?


And after countless hours of reading should I change AOS? not sure if is bad or not but gearbox is out so.....


I visited today Porsche Bolton and was lost in cars so many GT3 and so nice blue carrera targa GTS I would never chose that colour but in real that car looks amazing I will try to add picture later....so I was enjoying myself Sebastian keep asking me which one are we going to buy today Grin

My plan for today was to visit Hartech but these cars took me over before we back to our car it was 11:40 and they work till 11:30 frustrated NEXT TIME!

Tool is made from 6mm thick plate. The step down in the middle is 2mm leaving the part that clamps to the block 4mm thick - does that make sense?

AND DO NOT CHANGE YOUR IMS BEARING - JUST REMOVE THE OUTER SEAL, CHECK IT IS OK AND THEN PUT THE COVER PLATE BACK ON.

Just buy one from from Alex .. far easier .

You will need to lock the crank pully as well , a drill bit will do .

Dont even think of changing the IMS bearing your self , get the cover off and move the spindle up / down and in out to check for play .. if ok then flip off the black plastic seal on the bearing and leave well alone .

If you DO have play then get a garage to fit one .. you have the choice of a Porsche one which is a full engine strip or an after market one.

You will not have the tools neither the expertise to actually change it yourself so please .. just dont go there .

Oil cooler is what normally leaks .. i think from memory its an inlet mainifold off job to replace but if you look in the faq section you can download a workshop manual so have a look in there first .

Same! Could I enquire as to the cost of a cam lock as I'll be dismantling my car soonish, it has the original IMS cover so I'd like to swap it out for the later type with the better seal.

Makes sense given the cam chain on a 3.4 drives one cam..

I'll have to hunt one down, or get one made up. There's only the need for one cam lock, isn't there?

You only need to lock the camshaft which is driven from the end of the engine where the IMS bearing is fitted. The other bank is driven from the opposite end of the engine and it doesn't apply any significant force to the shaft at the IMS bearing end. That is also why you don't need to bother releasing that tensioner, just the two which apply force at the IMS bearing location.

Durrr! Of course, didn't even think of that.. I'm going to replace the cam chain tensioners and the IMS one too.

made a tool for my 3.4, nowhere near as nice as Alex's - I used a grinder, not a CNC mill!

I made it in 2 parts and bolted them together:



See dimensions here - he used a bent steel plate rather than alloy. Also bear in mind he has a boxster so the engine is backwards.

-------

77szymon - I did the IMS seal flip, see my thread linked below.

I'd be very tempted to just drop the engine if doing the oil cooler and AOS

See here for some great instructions: http://www.kellyanneporsche.com/enginedrop.htm

Thank you all for information,

Wasz - nice tool my plan is to do it same way next door I have aluminium manufacturer they do crazy stuff plenty of scrap metal around Laughing

deMort if they done it I think I can handle this job
Open Youtube Page
but I'm not planing to change it unless is somthing wrong with it my problem is to secure oil leak on flange and if bearing is ok only take off cover/seal as advised

I'm not happy to drop engine to change oil cooler but my engine look almost the same as from that clip 3:01 it is not as rusted on top but coolant is all over the place I will take a look tomorrow if we have enough space to take it out.

Just out of interest, this tool was the 1st thing that enabled me to survive in the initial stage of setting my business up. You guys don't know how much it means to my current success and I can only thank Porsche and their owners for it.
