Thread: Coolant Leak

I have coolant sitting at the base of the supercharger and the injectors. What would be the cause of this?

LIM gaskets leaking.

Thats what i thought it was. It is not leaking to bad so i am going to wait until winter break to tear it down. What would be more beneficial i plan on running a 3.4 pulley some time should i have the blower ported or the intake? I plan on doing 1.9 rockers while i do the LIM. I figure i might as well do some modding while everything is torn apart.

All of those that you listed are pretty good mods, but I would say your best mod would be getting a tuner. Putting some of those mods could possibly hurt performance if your tune isn't right. I see you have a "tuned PCM" but you can do better then that with a tuner. Just my 2 cents!!

Also take a look at your valve covers, do they show signs of leaking, might wanna think about doing the rear one if you haven't gotten the recall done and letting the dealer do the front one under the recall.

I would be concerned that if your LIM gaskets are leaking that you may also be getting coolant into the oil which could prove catastrophic to the connecting rod bearings.

They just did the recall so the vlave cover gasket should be fine. I am surprised they did not say anything about the coolant and try to make some money. I want to get a tuner when money allows it. I hope to have one by the time i do the gasket and what ever else i can afford. What are the choices for a tuner and what would be the best to use?

I just changed the oil a while ago (I the coolant has been there for a while) and there was no signs of coolant in it.

Well it doesnt take much coolant in the oil to cause issues and unless its huge amounts making it into the oil you wont be able to tell by visual inspection.

I use and recommend HP Tuners!!

HPTuners.com >> Performance At Your Fingertips

I might go ahead and do it now then. What other gaskets would i want to buy when i do this?

1. Intake gaskets (get the metal ones, from a L32)

2. Supercharger gasket with o-rings(2)

3. Fuel injector o-rings (12)

4. TB gasket

5. Coolant elbows (2)

6. Thermostat gasket & O-ring (recommend changing the thermostat)

Good luck!!

So it looks like about $100 for everything on zzp, i am going to autozone and napa to price stuff out too.

Yeah when I did mine it wasn't too much. Make sure to get a torque wrench.

I will be doing it at school and they have some nice snap on digital ones. I am asuming i will need to change my oil after i do this. It kinda sucks i just changed it and put in royal purple .

Yes you will, due to coolant and other foreign debris that will fall into the engine. Before you start to put it together, take some oil and pour it all over in the valley where the balance shaft is and all over the lifters. This help flush any coolant and debris down to the oil pan.

I guess you gotta do what you gotta do. I might take a chance and wait till next month to do it. It is a very small leak and has been there since i bought the car in March and i have not had any problems. I just decided now to look into it.

Well if you are certain it is a small leak, you may be okay for that period of time. When my LIM gaskets were leaking, some of the coolant was getting into the oil. It was leaking around the #3 cylinder. When I did the oil analysis it showed I had to cut my oil change intervals in half. It was a small leak, no spikes in iron or lead or anything that would indicate abnormal engine or bearing wear. It ultimately took me a couple months to get to it but I watched the oil like a hawk and had it tested a few times to make sure things werent getting progressively worse.

I check the oil on the dipstick every saturday when i check tires and everything else.
