It was a bad investment.
I spent way too much on a parts car. ($1500)
So far all I've used is the P-brake cables, the radiator, a window switch, a solenoid valve, the main fuse, some grommets and clips, some nuts and bolts, and the remote control. (which is $184 from Mazda.)
I could have bought all that for far less at the wrecker or Rockauto.
It's a rusty piece of crap and whenever I need a part because it's worn out or rusted all to hell, so is the part on the parts car. Lol
It's mine until the bylaw officer tells me to remove my derelict vehicle. Lol
At least it still looks "whole", with the body still intact.
It has been fun and I did learn a lot.
I remember the day after I got it.
I started it up, put it in neutral, and tromped it!
I wanted to see if it would blow up.
(I have no need for engine parts.)
It wouldn't blow!!
There is some sort of governor on it that wouldn't let it go past 7,200 RPMs.
That was a bit of a letdown.
I wanted to send a rod through the block, or right through the hood. Lol
For what it's worth, the FS-DE is a non-interference engine, as far as I know. I've never been in there and I've never snapped a belt or done a belt replacement, but that seems to be the consensus from most users. Despite this, it does sound like there have been exceptions.
Every new FS-DE engine is a non-interference engine.
But over time, both ends of the connecting rods wear and develop slack.
There is just enough slack to have the piston throw up far enough to hit a valve.
I assume that hard driving along with engine braking increases the wear.
When I first got my car and did my timing belt, all the parts suppliers listed the FS-DE engine as an interference engine.
To find out, I cut the timing belt off my parts car and hooked a drill up to my crankshaft, and spun it up.
Then I slowly rotated both camshafts around to see if any pistons would hit a valve and it didn't happen.
This only proves that my parts car is still a non-interference engine but I don't think it's the exception.
I'm pretty sure that more than 95% of our engines are still non-interference engines.
I believe that my DD is non-interference especially with the way I drive it, so I'm not changing my T-Belt again until it snaps.
My test may not have been 100% accurate because my drill only spun the crankshaft at a few hundred RPMs so the pistons may not have had enough inertia to take up any slack and go past normal TDC.
