Head is fubar!!

[JPherc774]

I've just this evening discovered why my 94 gt wouldn't start, it seems the alternator/AC compressor belt has snapped and gone inside the timing cover and fused to the cover infront of cam pulley resulting in the car jumping teeth and smushing the exhaust valves on the pistons :,( needless to say I need a new head but what's the best option, is it to get the head re worked with. We valves etc or get a 2nd hand head???? Also would I need to do anything with the pistons etc?!?? Any advice is most welcome............. Cheers

Should say re worked with new valves........

These are non interference engines, ie valves shouldn't hit the top of the piston.

Unless the head has been skimmed or there uprated pistons in your engine.

I went on auto data to check this out and it said 'beware these are interference engines?!' well it's definitely jumped teeth and I boroscoped the chamber and it seems as though they've hit, also when you wind it over it sounds like there is no compression and there's a strong smell of fuel from the air intake :S

they are non interferance engines dude

Is the 4efte on autodada ? I couldn't find it before.

Best bet would be to take the head off and investigate the damage, then fire up some pics.

I don't think do just punched in the make model and year and it came up with that, yeah I will whip the head off and have a closer look then upload the damage if needs be, cheers guys:)

Gimme a pm if u wanna replacement head mate I have one here

[pig666eon]

defo non interference i have a few taken apart here dude, tell them you want to see them cause it sounds well off that result like

my old engine jumped teeth before just reset it and no issues what so ever

there would be a smell of petrol as the timing is off, fuel is entering and not being burned properly not all depending on how much off the timing is

Deffo non-interference, mine had jumped 3 teeth (belt was absolutely mint when we took it off though, which was weird; still replaced it to be sure), and everything was fine once we reset it.
