HELP!! LARGE peaces of metal coming out cylinder

[rc5785]

I have a 2003 protege that has large peaces of ferrous metal inside of the #1 cylinder. would anyone happen to know what that could be?

^ A bad thing. Seriously though, I have no idea but it can't be all that great.

Broken piston?

Get an Inspection Camera down that Cylinder and take a look.

 

[dandan2]

either way source another motor or get ready to overbore the block and get a rebuild kit cause those piston walls are going to be scored.

VTCS/VICS screws and nuts probably.

Agh yes....Forgot about those pesky bastards.

pulled the intake last night all the screws were still in the butterfly valves. From what i have read on that recall it is on cars before my VIN. after i got all the peaces out the car runs pretty well maybe a bit rich but all in all good. But i guess now is good a time as any to learn how to work on a piston driven engine.

My other cars are a '91 rx7 with full bridgeport 13b-rew single turbo 40psi and a '94 rx7 streetported stock twins

Can you post a more close-up pick of that metal? Has any work been done on your car's intake area recently? I can't imagine how that stuff got in there, especially since all of your VICS screws are still in place.

This may sound dumb, but are you sure you looked at both sets of runners to make sure all of your screws are still in place? The VTCS screws are close to the engine block, but I think you have the physically move the top half of the intake manifold out of the way to check the VICS screws inside.

The only camera i have that works is the crap ass one on my phone. The only work that has been done to the car was replacing the coils about 3 months ago. I pulled the intake out completely. The metal looks like it could like it could be lead on the largest peace it looks to have been folded a few times and in a small part it looks to be machined. Took it for a drive last night the second set of runners seem to be opening later then before and when they do open it hesitates almost like fuel cut or miss fire. Did a compression test this morning average of 135 psi the one that the metal is coming out of was 128 psi.

the only other problem i have had with the is a CEL for the warm up threshold not within spec on bank 1 and I got that after the coils were replaced

Any time you have metal dancing around in a combustion chamber and bending up spark plug electrodes, I'd say continuing to drive the car is probably a bad idea. There's most likely some damage to the cylinder walls, possibly to the valves and the piston itself. At the very least, you should find the source of the metal fragments before firing the engine up again.

PSI should be 199 & 142 is minimum. 135 is starting to get low. Look again at the VICS. They are in the middle of the intake. You have to take it apart to inspect them. The way you say it drives and the number of pieces of metal in your pics says to me you lost 2 of them and they are laying loose in the intake. They are too big to go anywhere else. Does the car sound more rattly than usual at idle? That'd be those butterflys loose in the intake. Check it out before the others come loose and you have pieces in other cylinders.

+1, that compression is too low. Try doing a wet compression test to see if things get better.

Also, I may have missed this from above, but did you make sure that none of your spark plugs were damaged at all? That could lead to some hesitation.

the motor is toast guys it would not fire this morning when i was leaving for work. had it towed to the stealership they said just from the peaces that it was the butterfly valves and that it is NOT covered under the recall. my car was built less then 1000 after the VIN series for the recall....BS got an email to mazda corp customer service


so if nothing comes from the email to mazda i was thinking forged internals bored honed w/ 8.5:1 rebuilt head and garrett gt35r the only reason for the huge turbo is cause i have it in storage

 

[MAZDA_SPEED]

or get a replacement motor and keep it stock...IMO

sucks dude, but this isn't the first time I've heard of cars outside of the VIN recall range being affected by this.

Please let us know how it turns out.
