coolant seal savers, premature coolant seal failure prevention
 

well here it is... 13B engines from 1986 through 2002 with coolant seals located in the irons are subject to iron fatigue and possible coolant seal wall failure, the result is a failed coolant seal regardless of it's original condition.

granted this is not an issue that everyone will come across, the irons are milled differently and some have much thicker walls than others. even in some of those cases poorly maintained cooling systems will still result in broken coolant seal walls due to erosion.

this is an idea i put into application over a year ago in testing with irons in similar conditions to the above. the product is a sleeve that is placed inside the inner coolant seal channel to hold the seal even in the event one of the seal walls corrodes/fails.

this kit comes with a complete set of sleeves and inner/outer coolant seals designed to be used with these sleeves. the sleeves and seals are reusable to an extent, much moreso than the OEM coolant seals are. the inner seals are also not o-rings but square cut seals unlike many others who use round seals in the square peg hole, this allows the coolant seals more traction on all surfaces.

the engine must obviously be torn down to install these but as a prevention it is designed to buy time before coolant seals possibly fail again. in testing these sleeves performed still for the whole year of testing. i am not advocating tearing down a well running engine to install these but as an alternative to those who are and will be rebuilding your engines.



pricing for a set of seal savers and coolant seals for 2 rotor engines is $165 shipped to the US and $180 shipped worldwide. pricing for a 3 rotor engine is $240 to the US and $255 worldwide.

you can order by sending payment to me at paypal: ktm0012@sbcglobal.net and send me a PM on this board so i can expect the order to be made and get it taken care of.

i'm really feeling the enthusiasm here... :)


i know i know, it's not such an issue on the REW irons as the '86-91 engines but it still happens.

Lol I would have bought these, where were you 6000 miles ago? ? I rebuilt due to bad cooling seal. if this is an option next time around I'll do it for sure.

I just stumbled upon this in the 2nd gen product development and I think this is a fantastic idea.

My original engine died from coolant seal failure (I'm not sure if the irons failed as I didn't rebuild that engine, I rebuilt a spare core).

If I had known about these at the time of that rebuild I would have purchased a set without a second thought.

I'm hoping I won't need these soon as I only have 15,000 kilometers on my rebuild.

If/when I rebuild again I will put these in my car.

Are you sure this is a new idea? I have something similar I pick up from john finger from his old stash of parts.

good idea!

The first time I've seen this. Would like to see the long term results on them. Great idea.

Tried sending you a PM regarding purchasing this from you on March 26th but haven't received a reply. Is this still available?
