They showed me a couple of my own comments on this forum so I know they were watching this thread. I'm sure they probably still are but they don't care. Their last reply back to me was everything is fine get the catch can and let us know if it fixes it....everything is wonderful in the world.

I'm going to have to say Joe has the expertise here and they told me and stated here the tune is crap and could cause serious issues. His tuner (I assume the NIc D I have heard about locally) inspected the tune and came to this conclusion. Good chance my motor needs a rebuild - maybe because of this other shop and maybe not, my hood needs adjustment, I just wasted at least a few thousand on labor and I'll have to spend at least another 4 grand on labor for repair and retune, etc.

Maybe I'll get lucky and my motor just likes to leak a ton of pressure past unborked rings and a MMS catch can allows it to chug along. From all I've read quite a few people run into these issues and even if their ringlands/rings are damaged they stay together and run fine for at least some amount of time.

I will take the car to Cordes or just do a leakdown test myself and if it isn't damaged have them re-tune and just install the catch can. I think I chose the wrong shop trying to be a cheapass and I to do over I wish I would have done a leakdown test before deciding to put a blower on.
I didn't know where you lived but if you can take it to them thats a great choice. They do have the expertise to diagnose your problem and let you know your best options and yes many of us have had this issue. They'll treat you right. Once again good luck.

Man who are you? If you know the particular shop and you have read any of the stuff I've said here, which is straight up accurate, then I'm not sure why you think I'd like to take my car there again. They could have measured crankcase pressure after it blew the front seal. They didn't. They called it good and sent me on my way. They didn't even ask me what my goals were or what I wanted as a customer...big red flag. I honestly just let them do their thing as I assumed these guys are experts and know wtf they are doing and I only starting trying to figure out my issues after seals started blowing out running too much boost and again after I got home. On top of that they charged me more than I was quoted for installation. They didn't act like they even wanted to do my install I think their sales manager gave me a bs quote to get me in the door and the rest is what I've posted. I'm done with them they didn't reply to me. I don't know how you can look at the pics of my hood and think these guys cared about customer satisfaction or trying to do good by their customer.

Best options? Sure let me drive 9 hours roundtrip again to a place that might have nuked my motor, didn't really try to figure out why my front seal blew, charged more than I was quoted (not counting labor to replace front seal which they never told me they were until I was ready to leave okay cool), installed my hood like crap, and couldn't communicate with their customer or look out for their best interests. Sure let me hop in my car right now.

They might be amazing with LS motors but if someone asked me if I'd recommend them for LTs I'd say hell no.

After my car blew the front seal running 9-10psi the next day they said oh we did another LT1 vette with the same head unit and a 4.38 pulley made 8psi. I'm like why the hell would you start with a 4.00 pulley in the first place then? My experience was a shi!tshow if you ask me and I felt like I was the one person that cared about the health of my motor.

Not sure what your talking about I was saying go to CORDES. I've read everything you've said and I just asked you in an earlier post if you had contacted the other shop. I don't know the shop nor do I want to know it.

My bad I thought you were suggesting I take it back to the original shop not Cordes. Have a good one and thanks for your input.

No problem man I feel your pain cause I have been in your shoes and its ain't fun and always expensive if it did hurt the motor. Fingers crossed it didn't.

On 91 octane I would NOT run 16 degrees of timing on an Lt1.. even if the exhaust was breathing well (long tubes, no cats).. asking for trouble

I got the MMS wild catch can installed a few weeks ago and all has been well since with no oil leaks. I did find something that could have been causing some problems during the install. I was poking around with the pcv system and found the passenger side valve cover connection was at least partially blocked. It seems they removed the check valve ball on both sides in those oem quick connection fittings on the valve covers but on the passenger side the little "thing" that I assume is supposed to stop that ball from getting stuck in the connector was still in the connection and was lodged in there sideways (pic below). Looks to me this was probably at least partially if not almost completely blocking that pcv connection on the passenger side valve cover. The pic below is exactly how I found it.





MMS Wild can installed (I highly recommend this product)




It was time to change the procharger head unit oil last night since it's been about 500 miles since install. I'll have to say the shop that did the install hooked me up with the addon braided line procharger sells to make changing the head unit oil easier. It was a pleasant surprise they had installed that line to drain the oil because if not it would have meant I needed to remove the head unit to change the oil. I don't see any way I could have gotten to the bottom of that thing without removing the head unit. Also changed the engine oil even though it only had about 1500 miles on it. It looked clean no signs of metal in the oil.

If there's an issue with the motor I guess I'll just run it until it blows up and hope there's no damage to the block.

Playing catch up on this thread as I just blew oil all over the track at Laguna Seca on Wednesday.
18 minutes into first session. Got meatball flag. Pulled in to let it drip. Sadly, was done fro the day.

I have eForce. Stock tune. Colder plugs. Blew out front seal 2 years ago. Replaced by dealer. Added MM Catch Can.
No problems with car since. Was running mainly 3rd gear most of the track around 6-7K rmps. No drop in pressure. No rise in temps.

Thought maybe I overfilled the reservoir prior to going out. But, no signs of leaks or fluid anywhere near the tank, filler cap or dipstick.
Most of the droplets were all over the alternator and hood on the passenger side. Could just be where the serpentine belt flung the oil.

So, my question: Were would the oil be coming from? I cannot see anything obvious. And, I thought the eForce was fully contained.
Is it possible the front seal was only slightly leaking while being pushed hard? It stopped leaking. And, I was able to limp it back home.
