Oil Leak

Oil Leak
I have a 2014 Chevy Spark, 1.2L, 5 sp. Standard. This car seems to be leaking oil out of the front main seal. I was looking for information on the procedure for changing the seal but I can't seem to find anything. It looks pretty easy if the seal pops out the front. Looks like a nightmare if the front cover has to come off because the seal goes back through. Any information on this would be appreciated.
Thanks, Garner

RE: Oil Leak
My usual resources are coming up empty. Have you tried going through the Auto Zone web site?

RE: Oil Leak
No, I didn't think to try Auto Zone. I'll do that when I'm done here though! This car is a lot of fun to drive. Especially when you turn the Stabilitrac Off and find a curvy back road! And with the traction control On, I was super impressed with how it plowed through deep snow! But when it comes to working on it... forget it! You can't buy parts for it! I was to every parts store in town looking for a PCV valve. Every one told me it was "Special Order." I finally found one at the GM dealer. And even the GM dealer had to order the front seal for the engine. Tires? Very limited selection. And to look up repair procedures??? Nope! So I'm not sure what I will think of this vehicle? But I'll let you know after I've had it for a while. Wink

RE: Oil Leak
Ahhh ha ha! Color me surprised. "Unfortunately Auto Zone does not have repair information for your vehicle at this time." So...it's all just nuts and bolts. I'll wing it. Then I'll post the information.

RE: Oil Leak
OK, here's the scoop. I put a new PCV valve in while waiting for the seal to come in. (Had to order it.) The leak seemed to slow down considerably. So I am thinking that the root of the problem was the PCV. So I put a jack under the right side, to the rear of the front tire and raised that side of the vehicle. Jack stand for safety. Removed the tire and plastic inner fender. Removed the large plastic cover under the front attached to the front bumper cover. 19mm for the lug nuts. 92ft.lb. torque to tighten. 10mm socket, one bolt and two push pins in inner fender. 10mm for 3 bolts and 7mm for 4 screws in the front splash pan. I have NO idea what the correct way to change the A/C belt is??? Both my brother and I looked and couldn't find any means of adjustment! I took out 4 long bolts going through the compressor, 13mm socket. As the bolts came out the compressor spun sideways and we got the belt off. There's a tensioner on the main belt back towards the fire wall. Easy to get to through the fender well. Loosen 2 bolts, 13mm socket. Slip that belt off. (Note the routing for reinstallation.) There's a 1/2", square hole for adjusting the belt on installation. 17mm socket on the dampener pulley. Put some pry bars between the pulley and front cover and held tension on them as my brother smacked the end of the crank. My brother made a tool to do this so it didn't damage the crank. You could probably use a puller? When the pulley came off the seal was part way out of the cover. A hook tool removes it from the outside. Install the new seal. Reverse procedure to put everything together. A/C belt??? We set the compressor back in at an angle and used a bar and screwdriver to pry it around to get the bolts started. This CAN'T be the correct way to do it! But I didn't see another way! Anyway, so far, so good. Everything is together and No leaks.

As side notes, I would suggest getting new belts, PCV valve, and the seal all together. I couldn't find belts so I had to order them. So now I have to take stuff back apart. It would have been easier to do it all at once. But parts and information for this car both seem very difficult to acquire.

If anyone comes up with any information on the proper A/C belt installation, please post it! Other than that belt, the job was really pretty easy. I hope this helps someone.

RE: Oil Leak
A few years ago GM (and others?) started using "stretch to fit" belts on the AC. There's a variety of tools sold to help there and most look like a small curved ramp with a lip (only an inch or two in length) so you hang it on the pulley and turn the engine with a wrench to pop it on. I tried to work around that one day and my ordeal had the belt go too far and almost tore off the wire for the compressor clutch.

Anyway, the key is in the part number being weird, which means the stretch belt.

BTW, if the PCV valve was clogged you might want to check the rest of the small pipes to see if they are necked down with crud. Years ago I ran into a Chevy with the iron duke 4 banger that had a clogged system and blew out the front seal. What a mess that was. Same situation with the transverse engine and no room to work on that end inside the car.

RE: Oil Leak
NOW you tell me about the stretch belt???! Do you know how many bad words were said while I was fighting with that thing?!

Thanks for that information! I'm sure that I'm not the only one who didn't know that!

RE: Oil Leak
Don't shoot me, I'm only the messenger. (wink wink)

I stumbled on this within the last year and had to fumble through it myself on the first try. Stay with me here... because it was a vehicle that was already several years old that needed belts, which means it was a 2013 or 2014 Chevy van.

Here's' the cincher, which you may already know... these belts are made by AC / Delco, Continental, Gates, (NAPA) and Good Year. In my experience the Gates / NAPA belts last about half as long as the Good Year, which is also OEM Delco. Given the degree of difficulty (schedule wise) how often do you want to replace these things? 25k or 50 - 60k miles? Personally I will spend the extra $15 for the better belt and tell the boss to go shit in his hat. I'll also replace the idler and tensioner pulley for the alternator while in there, just to save down time.
