i found a "new" reman engine. 0 miles, never used. was purchased from malloy mazda little over a year ago. its been sitting in the guys garage. Does a new reman sittin for such a long time but never being used make a difference? hurt the engine? its a good deal that I dont want to pass up if all is well. thanks for the input.

 

it's not like malloy or mazda has them running laps waiting for you to buy it... if it was sealed up should be just a good find

 

I do not think it makes much difference to the various seal springs. The pressure they exert does not vary much depending on rotor position. A piston engine when left sitting a long time has valves springs left under contant high compression which weakens the valve springs.

The only concern I would have is if water (coolant) was left in the engine.
I once took apart a rebuild because the owner wanted to port it and then reassemble it. Evidentily it had set for a long time with straight water coolant in it and had noticeably signs of bad electrolysis between the iron and aluminum housings. This engine was not from one of the better Mazda rebuilders.

Malloy has a good reputation.

 

i know what you mean about the water (coolant) sitting in the engine, but from what I understand it has never been installed since he has gotten it. hence 0 miles. so that shouldnt be a problem. I just didnt know if an unused motor would have any problems from sitting. i didnt think it would but just wanted to double check to make sure.

 

I'm no expert but as long as it was sealed up well, or sat somewhere very dry, I THINK it should be fine. If not, I'd worry about rusted internals.

 

I would peek into the exhaust ports and give the motor a few turns. If things are bad inside that should show you enough.

Otherwise, it sounds like you have a good find. Especially if you offer a little less than he paid, which should save you big $$$.

1500-1600 shipped to my door. sounds like a deal to me for a "new" reman. 0 miles. Only problem is that the engine is 700-800 miles away so I wont be able to see it before I buy it. any suggestions?
