When I called a few months ago I was told the same thing. I think I talked to dave. He told me there was nothing the vec 3 could do for my car that the vec 2 with the latest firmware couldn't do. He said the advantages of the vec 3 could only be used on the newer models. I would like to have the...
The mechanic drained all the coolant out from the block before he removed the heads. He noticed when the took the head bolts out there was coolant in the bolt holes and he knew it wasn't form his removal since all the coolant was already drained.
Good luck with your rebuild!
Here is a shot of the broken valve guides. The mystery of why this all happened (coolant being pressurized and flying out while on the dyno) has come to light. It had nothing to do with detonation. It was an oversight on my amateur mechanical skills. When I installed the heads I didn't clean out...
Sorry to hear of your misfortune. You and I both started on the self installed s/c mission about the same time. I read many of your posts and got a lot of good info from them. I don't know if you read my post but I had similar problems with detonation which forced me to take the heads off again...
Tony,
He gave me the 2 broken guides but I don't know the top from the bottom:(. It was broken off where the seal sits. I will post a picture when I get the car back because the parts are at the shop. I did look at the broken pieces for a spot where a clip could go and I didn't see any. I think...
Picked up the heads today and he showed me where the 2 guides were broken. They were both on the same spot on each head. He said the guides were supposed to have C- clips in them and none of them did. He also showed me the teflon seals which he say's haven't been used in 10 years. They have been...
Talked to the machine shop (Lorenzo's Fast Flow Cylinder Heads- Langhorn, Pa) today about my heads and there is a problem with them besides the crappy seals. A valve guide on each side of the head in the same spot is broken. One of the valves is very restricted in it's movement. He said I am...
Here is an update on my car-
Engine is apart and head gaskets are fine. Somehow the pressure lifted the heads up. I torqued them according to the manual- 35lbs first, then 90 lbs. Maybe they needed more with the s/c. I am having the valve seals replaced as I am told they are a much older...
However you are doing it- your write ups are just what I was looking for. Great work- I was wondering where I would be able to learn all the tuning dynamics.
Can you tell me how you set up the vec for the wideband. I read your writeup on wiring but I need the actual vec setting. I went into the...
I have read this post a few times and still am not clear. I would like to log both banks with my vec 2, and i would like 2 a/f gauges. Can I do this with 2 LC-1's and 2 air fuel gauges?
Is there anything else I would need?
I would like to install the sensors in the rear 02 sensor location. I...
Yes they are local in Huntingdon Valley on rte 63. They will know Vipers when I get done with them. :omg: JD's Auto Repair and Performance Center
V10 Thanks for the info. They were one of the only places around I could find with a dyno. Joe - the owner took a few minutes to get the hang of the...
Thanks Jack. I will be looking to address all of those items. Quick question- does it matter what size the combustion chambers are if the car is tuned for them?
Gary
Sean,
I have ordered many other products and spent plenty of money with your company.
I knew there was a problem and I was trying to get help from wherever I could. I sent you and Tony my log files and the profile I was using. I am new to tuning - I just wish one of you said let's play it safe...
Sean,
The first thing they did was a pressure test on the fill bottle. I asked about it possibly being the cap. I was told that the cap releases at 17lbs, but doesn't shoot out like a geyser like this did. Also, the first time coolant came out it came from the overflow bottle in the facia. The...
Yes it does seem high - I asked the shop and he said that is the cost for 20 hours- if it is less he will charge me less. I am going to tell him that I checked and it usually takes 8 to 10 hours.
I can't really drive it home because it may hydrolock with the antifreeze in the cylinders, so I...
