I'm Over It. Engine Blew Up.

[FPVF6355]

I'll get the timing cover and head off this week.

Flush out the block and check rods and bearings, bottom end might be alright, as it happened at low revs and very quickly.

Could be just a complete valve job and new chain etc, cars never overheated or anything.

Talked with brother inlaw last night over a few tequilas, (mechanic) recons he can get the head done at mates rates.

Not sure what a full set of valves and rockers are worth, I presume the NA engines have the same rockers ?

If con rods are bent I'll propably go a new short motor, and rebuild head.

Does anyone know if you can take out the ecu and have it's functions checked without being connected to a car ?

Cheers.

Has the guide broken on the right side of the motor? we have seen a few of these break the plastic part of the guide and causes cams to jump teeth

?????

There are electronics people that can test ecu's, your mechanic should know some

If I remember correctly the valves are worth approx $30 each

maybe it was overfuelling cos the timing was off ?? I think ratter is right, timing guides are becoming very common.

Once I get the timing cover off, I should be able to check the tensioner properly, but at the moment the chain is tight.

I just pulled off the fuel reg again, and the plastic filter on it is cracked, which goes around the piston of the reg, when you cock the cracked filter the crack holds the piston from being able to move.

I suspect the fuel pressure regulator might have jammed shut, this would over fuel on each opening of injectors. Then with over fueling the piston over compression could have jumped the timing and crunch time began.

When I had the injectors tested, even though they all flow matched, and pulsed, I did notice how much fuel they deliver (alot). it could easily flood an engine if the reg was stuck closed, and fuel was dosing too heavy at full pump pressure.

So to me I think it's a combination of worn parts.

Fule pressure reg / timing chain tensioner / and higher flow 60lb injectors.

This is the only obvious thing I found.

There's bits of the filter missing, that might have jammed the piston on the fuel regulator.

I'm not 100% sure, but the 5 cent plastic filter seems pretty stupid idea (Why filter fuel going back to the tank, with a brittle plastic part ?)

the tensioner which normally breaks can be seen with the rocker cover off

I looked down with a torch, the tensioner and guides look OK.

It's definately caused by over fueling (over compression)

if your timing is off the chain has obviously skipped. and if your fuel reg is buggered, it would just circulate back to the tank. your injectors have to be buggered and all jammed wide open to let that much fuel in, and even then it cant get to the sump. are u sure there was not way too much oil in ? oil does smell fuelly when hot/old.

It definately took on about 2 - 4ltrs fuel into the pistons over 20 seconds or so. I just recently changed the oil, and was pretty anal about oil level. After I dumped it, you could easily tell it was mixed with alot of petrol.

Something someone did mention to me the same day, before it happened was my voltage gauge on the turbo timer is always functioning @ 14.5 volts. He said I should be concerned that their might be an earthing issue in the car somewhere, because he thought that was too high.

The timer keeps a record of max voltage, highest recorded was 15.6 volts.

once the motors out I'll be checking all the electrics and earth straps etc. at some stage I'm expecting to find weak connections to sensors or ecu connections.

I thinks it's a combination of issues.

Original fuel reg

high volume injectors

150,000k's

recently tuned to boost earlier (boost starts building around 1500rpm and increased from max 14.5 to max 15.5psi

and a possible software glitch holding injectors open, maybe due to a poor earth or voltage spike ?????????

Either way, once its back together, I'll reset back to stock ford ecu settings, stock injectors, and sell it.

I know you must be VERY excited about the Getz but wouldn't it be easier to get a long BA motor off ebay and just get the car going again? I did similar as a temporary measure but now I think I'll just leave the BA motor in. It goes real well anyways
