WildPlumDx Posted August 3, 2008 Share Posted August 3, 2008 yesterday i get a call from my sister and she says my carz died come help me, great last thing i wanna hear! anyways turn up there couldnt really do much called the aa dude turns up and straight away he said it was the cambelt anyways got it home and he was right its gone, engines a 4g92 sohc 1500 or 1600 so i might get lucky he said as the twin cams dont get so lucky, thing is the car still turned over doesnt make any horrid noises, does anyone know if this engine has valve clearance ? i guess it just snapped at the right time, anyways i dont think its one of those things you really know till you pull the head off or hook up a new cam belt and try turn it over by hand first, guess i'll find out soon enough Quote Link to comment Share on other sites More sharing options...
MACKAZ Posted August 3, 2008 Share Posted August 3, 2008 Ring rapeco and enquire about belt. While doing so their book should state if its an "interference" engine. If not, should be all goodly. if so bent valve city. Quote Link to comment Share on other sites More sharing options...
lowlancer Posted August 3, 2008 Share Posted August 3, 2008 99% sure they're non-interference but fuel will know for certain Quote Link to comment Share on other sites More sharing options...
fuel Posted August 3, 2008 Share Posted August 3, 2008 sorry but all multi-valve Mitsubishi engines are interference engines - only ones which aren't are the SOHC 8V motors. 4G92 is 1600cc. You may get lucky, but most likely it would have bent valves. Quote Link to comment Share on other sites More sharing options...
WildPlumDx Posted August 4, 2008 Author Share Posted August 4, 2008 gutted what would you do fuel whip the head off or try to the timing belt and then just turn her over by hand ? if valves are poked wouldnt it be cheaper getting a whole new second hand head ? no ?

thminiman Posted August 4, 2008 Share Posted August 4, 2008 id rip the head off not sure on second hand market but you are likely correct about just rocking a new head Quote Link to comment Share on other sites More sharing options...
Dell'orto Posted August 4, 2008 Share Posted August 4, 2008 If its an interference motor, you'd be very lucky if it hasnt punched a hole through a piston or two. Quote Link to comment Share on other sites More sharing options...
fuel Posted August 4, 2008 Share Posted August 4, 2008 it would have most likely put dents in the piston but that's about it. It's not often valves punch through pistons on Mitsubishi motors when the cambelt snaps, just usually half the valves get bent. I replaced a head on a mates 4G67 DOHC when the cambelt snapped, only slight dents on the pistons but 8 valves bent enough so they wouldn't close. It seems they are interference, but not quite extreme on the interference scale if that makes sense. Quote Link to comment Share on other sites More sharing options...
Hemi Posted August 4, 2008 Share Posted August 4, 2008 easy way , put another belt on and turn over ... itll either not work or start have have somehorrible huffing noisies the odds of snapping another belt at turn over speeds is just about non existant as the valves will abosorb the impact before the belt does (which will be fucked anyhow) . i know this .. cos i forgot to tighten the tensioner on a hiace 2l and it went really well till i revved it to 5 k then shut if off.

Dell'orto Posted August 4, 2008 Share Posted August 4, 2008 4G63. Apparently "just came to a hault" Note the valve in number one Was as how they found it when the removed the head. Quote Link to comment Share on other sites More sharing options...
WildPlumDx Posted August 4, 2008 Author Share Posted August 4, 2008 sweet might try hook the nelt up and see, are they gay to work on being fwd motor it looks gay also do they have a balance shaft belt? got a price online for cambelt 35bux! cheap as ooh and can any one send me a manual for this engine for the timing and junk ?

Ke36 Posted August 4, 2008 Share Posted August 4, 2008 yea will have balance shaft belt replace that as well, if its not snapped all ready Quote Link to comment Share on other sites More sharing options...
fuel Posted August 4, 2008 Share Posted August 4, 2008 4G92 wont have a balance shaft belt as they don't have balance shafts. and yeah Dellorto I've seen that 4G63 before, I was going to say I've seen a messy 4G63 cambelt breakage but that is just an extreme case. 9/10 times you can get away with another head or replace the valves. I have a manual for the 4G92 engine on my computer, let me know your e-mail address and I'll send it through. Quote Link to comment Share on other sites More sharing options...

Nah, that was from one of my customers workshops. I dunno if the 92's are as bad, but I've seen maybe 40% of 63's do that when a belt breaks.

sholdowa Posted August 7, 2008 Share Posted August 7, 2008 Gets real expensive when it's a Maserati v6... tosser service wanker taking shortcuts on the service. Tensioner was tight as, just as loose as you could get. Quote Link to comment Share on other sites More sharing options...
