Direct oil feed

[Alan Mackew]

selling is certainly an option. Having owned many sports cars and speciall interest cars over the years, from vintage to modern, sensible decisions wthen it comes to cars are not my Forte.

I owned a 1997 MGF and a Caterham Super Seven a few tears back both fitted with the same Rover K Series engines (also in the early Elise ) these engines are renown for head gasket failure and it happened to me on both of my cars at different times, I still really liked them, however.

The difference with the Boxster is apparently failure is without warning and expensive to fix whereas on both my K Series engines there was warning in the form o obvious coolant leak from the head gasket and relatively cheap to fix.

In many respects the Boxster is the best all round useable sports car I have owned apart from the spectre of the IMS ( an unforgivable fault in a car from a manufacturer with such a fine history.)

Cheers Alan

Just joking Though I did trade my Box last November for of all things an off road Pickup truck. I never did the IMSB and the car gave me 6 years/55k miles of enjoyment (Most fun car I ever had). I wasn't using it much and I needed something to help me move and haul new toys. But I did think while reading this thread that I never think about my IMSB exploding and should I change it and what type to change too.

SO much controversy about the IMSB, seriousness (or not), root-cause and solutions.

Is it the faulty seal and corrosive oil that gets sucked in?
Is it too much load on the bearing?
Is it poor lubrication?
Is it all of the above?

Plenty of debate out there from a lot of smart folks. Who often don't agree.

After reviewing them all, I decided on the EPS roller bearing and oil feed. Is it inferior to the LN solution? Is it better? I don't know. But after reading fdbk from all the experts it made sense to me. It's not the cheapest option but reasonably priced. ...and pretty sure it's better than what came out of the factory.

LN seems to have the best and well-known reputation and I expect if installed by an approved technician will add to resale value more than other options.

If you know or anticipate that a clutch job is required, seems practical for most of us to inspect and likely replace the bearing and a variety of seals and wearable items -- if only for preventative maintenance. I like to do my own work but don't like frequently pulling the tranny so it's worth doing a little more work and spending a little more to reduce risk of failures.

Did you punch a hole behind the oil pump or did you use an external feed? The EPS system intrigued me even though, as you said, the LN system is more popular.

Will punch behind the oil pump per their recommendations but haven't done it yet!

Yeah, that's mainly the part that intrigued me. I was actually wondering about using a new OEM bearing, pulling off the seals and using the EPS oil feed method. But I have a Tiptronic, so unless I have a reason to go in there I probably won't do it.

Let us know how it goes, please!
