1989 metro valves? maybe

Well, i am the one that has the issues with the compression on the #2 cylinder and i thought it was just hesitating. well. i thought i would try to find my flow test fitting but i cant, so i thought i would try to see if i can hear the air coming out of the throttle body while the car was running, so i took the air cleaner off, started the car and started to listen, all i heard was sucking, so i revved it up a smidge and then it backfired through the tbi while my ear was right close, that hurt lol. so on old cars, backfiring is usually because of bad timing or some other ignition source or poor carberation. is that the same? or is it just a valve? or is it there was too much fuel in the cylinder that wasnt yet combusted and then it popped from heat or what? im kinda stuck.

I will do my best to try to answer some of your questions, and give my input. As I stated before when listening in to the throttle body disconnect the coil wire first; at least I think that I stated that part; eather way, sorry about your ear! I don’t know what flow test your speaking of, or what kind of port you are looking for, I don’t claim to know it all, I have 3, 3cyl GEO’s I overhauled a few and love them all. have I have been a mechanic for 40 years and was rebuilding one today. With 15 lbs of compression it is time to take the head off! You will then find your problem unless you have a scope that you can put down inside of the spark plug hole to see the damage. Re building a GEO 3 Cyl is easy. You wont need to even take the engine out. Pull the head with the intake on it. Drop the oil pan. Unbolt the three rods push the pistons up out of the block. Send the head out to be rebuilt or I could walk you through it Maybe? Spend $85. for a head set. $75. For standard size rings, spend $9.00 for an oil pan gasket. That’s it. As easy as rebuilding a lawn mower engine.

i've got the rebuild part down for the most part but these could be different you know, its just the running part for these cars lol. I've had 3 beetles and 2 corvairs just in the last year, the body's were in great shape but they all had no motors or they were stuck so i can rebuild without a problem. I like projects and keep selling the cars to make a little profit and get another project. I'm stickin with the fuel miser this time though i think. The metro personality is what i'm not used to lol. When i was listening to the throttle body i had the car running, i had never done it that way before, i always used what i call a flow test. I couldnt find my fitting so i made another one, i take an old spark plug, take all the inerds out of it and then i take an air fitting and weld it into it and thread it into the plug hole of the desired cylinder when the cylinder is on its compression stroke and at tdc and turn the air on and listen and use some thin paper at the carb and exhaust to find the bad valve(s). anyways, I attempted to take the valve cover off of this beast today and it did not want to come off, is there some kind of trick, unless i am mistaken, there are only 4 nuts holding the valve cover on right? And i think i might just ask my neighbor tomorow to see if he has a scope, i have 2 mechanic shops less than a hundred yards away from me on either side, that can be a plus sometimes haha. Thanks again for any advice.

well, so it turns out, it was a burnt valve on the #2 cylinder. I still have only 150 psi on 2 of the 3 cylinders and 160 on the other. I think i will keep checkin and watching the compression on the engine and if it gets any lower then i'll just rebuild her. For the extra 35 dollars in a new top end gasket kit and 40 dollars or so for the bottom end gasket kid and then new rings at 20 bucks it's not bad at all. All the parts that i listed being from ebay anyways. New plugs and wires and it'll be just like new.

i would say that it could be the catalytic converter but the only way to really find out is to cut the pipe and look in there.. well, the only way that i think is most accurate. then if it's ok then purchase adapters and muffler clamps and put it back together or just weld it if you have access.. Before you do anything drastic though, and probably the first thing you ought to do is to do a compression test and that could tell you everything you need to know. But if it is still within specs, between 150 and 195 psi then check the cat, then, if all that checks out then a tune up, could b weak spark but highly unlikely. just roll with the punches i reckon, keep us posted

Sometimes when I am sitting at a light. I release the clutch, and the car lurches and bucks like I am a new driver (I have been driving stick for 25 years). The air cleaner is new, The oil is due for a change, its got a new clutch (less than 5000 kilometres on the clutch). Weirdest thing today, I was sitting at a light on a steep hill, it went into first and bogged right down, no HP at all. For about an hour after that didn't matter if I was in 1st or 5th, I had no go juice at all.
mine is a 1995 2dr with 300,000 kilometres

timing gear

the timing gear on my 95 metro 1.3 L broke and I ordered a new one. the problem is that the engine has been replaced before I bought it and i guess the engine is diff. from the original. the new gear came and it only had four bolt holes for the belt pulley and the old one has five holes. does anyone out there know how to identify the year of my engine with the engine I.D. number??? Or do I have to keep ordering pulleys at 35 bucks a pop till I get the right one?? The dealers and junkyards are no help....
