the FD i originally was to rebuild ended up with more damage than i thought. So i sought out to find another for a decent price, 2 yrs later i have found one purchased it and am in process of getting it running in STOCK condition for now. I do have plans for it after it is rolling, but untill then heres the story:

blk/blk base w/ clean body minus dent in pasenger side rear quarter panel 130k on the clock. the previouse owner did not sound very mechanically savy. but the story i got is he recieved the car with a blown motor. he ordered a mazda reman but his mechanic friend that was to do the work for him couldnt for whatever reason. so the motor sat for about a year and was finally put in along with a brand new engine harness, vacuum lines, walboro, 6-puck clutch and flywheel. but they were never able to get it running, so a compression test was done and
only 1 face on the rear rotor had compression. the car then sat for about another year.

That being said i have verified all of the above myself minus the clutch and flywheel to be true. videos follow

Now as is i have injected MMO into the chambers and am letting it sit in hopes to 'unstuck' the apex seals. no i did not use ATF as it is a new reman w/ no carbon build up. i will be checking compression again in a few days but by what has been told to me this motor sat for almost 2 years without really being turned over at all so my questions.

Am i shooting for the stars here in tring to get the seals unstuck because the springs are actually flatened?
And does anyone have anyother suggestions to releasing the seals without rebuild?

if i end up needing to restack the motor it will be coming out only to be turned into a HP whore and while thats being worked ill source a low mile stock replacment to sort out the drivetrain and suspension. :) always have a spare!

let me know what you think

That is really odd. The seals may be stuck and the chances of them getting un stuck are not that good you may want to try seafoam too. Sorry but looks like a rebuild is in your future. Hopefully everything is like new inside but hopefully a stuck seal did not harm anything and your rebuild will be cheap and i would definitly port it;).

seafoam is really supposed to be used while running so thats kinda the problem. but it seems just from sitting for 2 years no rotation it has 1 stuck seal in the real and 2 in the front, weather from dried out assembly lube or flattend seals. i dont see any internals being damaged from this but stranger things have happened. and honestly after a few days if its not good to go a last ditch effert would be to tow it down the street and pop the clutch in second....not really what i want to do especially if the springs are flattend.

I would try pop starting it but i would not reccommend it to someone else that might hurt it but cant say for sure and it is your car. The seafoam i am talking about is the spray it's kinda like wd40. But like i said you will most likely need a rebuild which sucks but you chance for porting and big hp just opended up.

As I posted on the other forum I offer the best priced rebuilt shortblocks around, let me know if it comes to that if you want a quick turnaround time. :)

$2750.00 Shipped with Streetport and good condition used housings. Thats cheaper than a reman and it isnt a gamble like a reman :)

little update as most threads have crappy questions then die.

well ripped of the turbos today to see if i could free the apex seals or see if the motor was toast. as stated before this motor was supposedly a mazda reman unable to start. and it looks like it is from the outside and kinda on the inside, looks like someone tried to start it. but look at what iv found.

this is the front turbo i havent looked at the back yet

so needless to say this engine is toast as it sits. i will be tearing it out the rest of this week hopefully friday and then tear down saturday to see if i can find exactly what went through this engine but i have a pretty good idea already. the next pic can explain alittle

and some people wonder y there shit breaks this couldnt have anything to do with it
