Need help on a decision

[LudviG]

My GF's 93 lancer 1.3 died on me the other day. Just died, there was no banging or sound, just like when you cut ignition. After further investigation it was just what i feared for, the cam belt was ripped in half. But since there where no bangs or other sounds when the belt broke, is it worth changing at and hope no valves are ruined? I have always believed that if something break there will be sound, but I am not sure....

What you guys reckon?

It is possible nothing else has been damaged. It depends on a bit of luck and timing, and also how the engine is designed.
I had the same years back on a Vauxhall 1.8. Cambelt snapped at around 70mph. Result was only 5 slightly bent valves and no other damage.

for how much a belt and fitting would cost it is worth trying just make sure it is timmed up correctly and manually turn the engine before you start it.

If you can get a look at a mechanics cambelt book, it will tell you if it is an interference engine or not! If you get stuck, i may be able to ring a mechanic mate of mine to find out.

autodata says 93 lancer 4g13 has been identified as an interference type engine.

firstly check as mentioned above if you engine is a clearance or interferance fit form the valves on the pistons. if it is clearance fit then there will be no valve damage.
If it is interfeance then, personally i would remove the rocker cover and inlet manifold and check valve positions on the cams to see if any are bent or stuck in the open position when the cam shaft is rotated, as a first resort. but you will have to make sure the pistons don't get in the way of them opening. you should ba able to see the top of the valve stem through the spring, which will be under the cam follow.
if all the valves open and close and look like the are sealing on the valves seats on the inlet side, then to make completely sure none of the valves are bent. close each valve in turn by turning the cam shaft and pour a bit of petrol on the back of the valve and see if it stays there for 10mins, if it leaks through to the cylinder the valve is probably bent to some small degree that you could not visually see, or the valve seats are damaged anyway.
you will have to do the same with the exhaust valves as well.so exhaust manifold off to check those.

What will interference engine say?

[c0xxy]

It means the valves can hit the pistons. Do what Dave said or replace belt and compression test it.

I will try that i belive, just need to read it carefully, since technical english is not my best language

Would'nt there be alot of noise if the pistons hit the valves?

[c0xxy]

I had a belt stretch allowing the exhaust cam to skip a tooth and bend all 8 exhaust valves with out much noise.

I opened the rocker cover today, and turned the cam to look. All valves opens and closes, but i cant really see the valves. But i reckon i will try to change the cam belt and see if it is alive Will it be ok to fasten the rocker cover again and see if the car is alive before i change the gasket?

my mates evo was out to the point where you could hear the contact between pistons and the valves.
was so bad that when the bonnet was closed it sounded like the bottom end had let go.
he retimed it and every thing was perfect .so for the price of a belt its worth a go imo

Chuck a belt on it, fire it up and do a compression test on it - its the only way to tell.

Just coz a book says it an interference engine I would pay much attention to it. I have worked on interference engines which have hit and non interference that have!

[LudviG]

Yeah, i am trying this over the weekend. The car was only planned to last till over this winter anyway Worth a try imo.

[LudviG]

The lancer is sadly officially dead.......

Looking for a new car ATM. Anyone got any experience with Peugot 207 2005 -->?

I have read alot about peugot lately, and the electrical issues they used to have, should be better on the later models.

Gearboxes is the first time i hear about, shall try to read up on it. I know alot Carismas has renault gear boxes.

[adamvortex]

my misses works for a gearbox company & trust me all french boxes are crap,they have more peugots & citroens than any other. as for carisma's some may be good some maybe crap its the luck of the draw. saying that tho my misses has had about 3 carisma gearbox jobs in the last 9 years not bad for a renault 19 box!
The carisma was never made in japan it was made by nedcar in holland,hence the pre-ford volvo project which never worked out,the carisma is just a S40 with mitsubishi clothing.
mitsubishi scrapped the carisma in the end
As for electronics anything fitted with magneti marelli (french junk) inside will almost definetly fail in time, we started to use there electronics on the rally car at ralliart my god it did nothing but cause problems.
