I recently purchased a 98 Metro in outstanding condition to replace my tired 99 swift. As this is my first 3 cyl, I'm interested to hear if others make a similar "rattle" under load when cold. My first thought was slightly loose main bearings, but once the engine warms up well, the noise goes away and it's smooth and quiet as can be. so is this piston slap perhaps? do they all do this?

Thanks,
Russ

Is it a rattle or a tick? The g10 is notorious for sticky lifters when cold. All mine have done it.

I'm pretty sure it's not lifters, as it's deeper in tone and is mostly apparent when under a slight load or when reved cold. I hesitate to call it a knock either, as I tend to only claim a knock on a sound that makes me want to pull over and call triple A ;). to me, it acts like loose main bearings in that it's only audible under a load, but if it was mains then it wouldn't go away when warmed up. which is why I tend to think piston slap which goes away after the pistons heat up and expand in the bores. are the 3 cyl pistons forged? the car has 158000 on it BTW. but clean as a pin and obviously well cared for/serviced.

Thanks,

Russ

It's normal, it's piston slap. Nothing to worry about, it's common and doesn't hurt anything.

Sounds like you've got it figured out, but I'll throw out another vote for piston slap. I hear it in mine as well.

Guess it's time to sum up what I've learned since starting this thread. After doing a wet compression test I was pretty sure it had a burnt valve or two, so I decided to pull the head and take care of that. all three exhaust valves were somewhat pitted, so they were replaced with stainless variants. the intakes were refaced and lapped, and all the stem seals were replaced. the cylinders were still showing crosshatch, but I couldn't see bolting the head back on without inspecting the pistons and at least replacing the rings. it's just to easy to do at this stage. The pistons miked about .003 wear at the bottom of the skirts, so rather than scrape carbon from the ring grooves and hope for the best I replaced the pistons along with the rings. well worth the $66.93 investment IMHO. bottom line is that it has more power now, runs smoother at idle, and has no more cold start rattle. Russ is a happy boy again!
Thanks for the input,
Russ

Wow?
Not my first rodeo. Timing doesn't add material to pistons or cylinder walls. Yes, every Suzuki engine with piston slap could be disassembled and rebuilt immediately, but does it make sense in most cases. No. That's all I was saying. There was no mention of oil burning or rough running in the first post, only minor noise cold only. Having owned hundreds and repaired that many again, I've seen a lot of them with piston slap cold that serve there purpose just fine if the rings and valves are doing ok still.
Cracked and broken skirts are a different case, but this did not sound like a case of major damage.

you caught me
my bad
My sudgestion for advancement of the timing is maybe the knock your hearing is retarded timing
causing pinging

.
My 87 T3 rattle like piston slap under load..... but went away when I readjusted the MAF
(weak spring tention) IE adding to much fuel
Just saying when you think it one thing sometimes it not
.
and again if you noticed sorry for me spell'n
My excuse.....Ate alot of paint chips as a kid....Thats my story and I'm sticking to it.!

You sir are correct piston slap is very normal!!!I would suggest put the car in neutral rev the engine up to 1500 rpm .Then take it to 2000 rpm hold that for 10 minutes make sure you time it.Now take it to 5000 rpm hold that if the rattling goes away that's fine but don't stop now the final step. floor it you should hear a loud bang noise. The noise that was in question should no longer be present it should go away along with the side of your block.This repair is called RDD that stands for Rapid Dynamic Disassembly. BS aside JV&S is correct 9 out of 10 times
Best of luck!!!!
