    Took apart the heads yesterday. Turns out these heads have rotators on all the valves - something which Comp Cams said nothing about in their notes for the cam kit. The stock rotators are too thick for the correct spring height, so now I have to order 16 rotator eliminators. Comp sells a set...

    Camshaft Install/Rocker Adjustment How-To?

    OK, that sounds about like what I've been reading/thinking. It seems pretty simple, I just want to make sure I'm 100% on the process. On the T4 oil - I was told last week that Rotella stopped putting in the zinc about a year ago. Anybody heard anything about that?

    Camshaft Install/Rocker Adjustment How-To?

    I've literally never installed a cam before and have no idea how to properly install and then adjust the valve lash. Does anyone have a good how-to for this? I want to make sure I get everything right - particularly valve lash. Any comments on the overall cam install process would be MUCH...

    I compared the 11-207-3 (270H grind) to the 11-238-3 (XE262H grind) and the only difference I could see was that the 270H has a little more intake lift/duration than the 262. The descriptions state: 11-207-3 (270H grind) 11-238-3 (XE262H grind) That tells me the 110 lsa should not be a...

    Well I went ahead and got the complete Comp Cams K-kit for the 270H cam. I'll be very interested to see how it runs. I'm pretty sure my compression is down around 8.5:1 or so, so I hope that doesn't result in it being a dog. As you say the cam description does not call for a minimum CR, so we...

    Visited the head builder today. He said my heads are perfect. No issues at all. So I guess the 454 is not an interference engine after all! He took a look at my lifters and said they are whooped though. Said I need a cam. Any opinions on the Comp Cams Magnum 270H? I know it's a fairly big cam...

    I dunno man, A brand new Melling High-Volume oil pump is $45. I'm thinking it might be money well spent in time and capacity over a unit with 153k miles on it. I don't mind taking stuff apart for repair/overhaul but I'm thinking this might be too much lol. Good info on it though. I might just...

    Good idea. I was debating what I should do with the pump. Should I replace the pump and/or screen or just clean it? As to the viton - I was looking at using the Fel-Pro Permadry line of gaskets. Is that what you are talking about?

    Especially considering we just had a baby 6 weeks ago. I told her not to try to lift it, but I guess she took it as a challenge. I thought Wumbo's avatar was perfect too.

    Dude... I don't even want to talk about it. 3 jobs Doctoral school 4 kids I could go on, but I think you get the idea. I have spent many a night getting this kind of thing done at past midnight. I just try to not drop too many wrenches or cuss too loud so I don't piss off the neighbors too bad!

    For those of you who saw my A/C and Rant thread posts you may have seen that the day after I got my A/C running again the engine decided to puke. I had gone out to fire it up and make sure that the new A/C had not leaked over night. Sitting in the driveway, it ran for about two minutes (like...

    Hmm. Can't upload pics from my phone. I'll try again on my PC tomorrow.

    Charging a new A/C system

    All fun and games until you blow the engine. Litteraly the morning after I finally got the AC working (it took 6 years) the engine wiped the timing gear. I had started in in the driveway to see if the AC leaked overnight. It ran like crap for two minutes, then died. Here's the damage. Yes, I...

    Charging a new A/C system

    Next update: success! I got a different can adapter that worked a LOT better, and allowed the sensor to cycle the compressor on it's own. I was able to get about another can full in it before it started cycling. I keep going until the pressures looked ok. See pic below. Considering it was over...

    Charging a new A/C system

    Ok, that makes me feel better. I resorted to doing just that and was wondering what the hell I was doing wrong. Part of my problem was a lack of adapters for the freon cans. This EPA valve thing made life very difficult. I know you guys mentioned this, but I figured the gauge kit would come...

    Charging a new A/C system

    So the crazy high low side pressure, and frosted over lower evap tube was normal for a low freon situation? How long should it take to suck in the freon? I swear I was working on it for an hour and I maybe got 12-16oz of freon into the system. It seemed to take forreeevvveeerrrrr. Again, I...

    Charging a new A/C system

    Brand new system, so the evaporator was new - no old o-tube. I used the o-tube I had in the old system. It was brand new and never run, it just sat there in the pipe for 3 years. Is it possible it's stuck or plugged? If I remember right, it was one of the auto-adjusting ones. I'm going to try...

    Charging a new A/C system

    Long story short: complete failure. I tried to get the freon in it, but the low side pressure climbed crazy high (100+) and it stopped taking freon. I got maybe 16oz of freon in it. The bottom pipe on the evaporator iced up and the compressor and suction/discharge lines got super hot. I have...

    Charging a new A/C system

    Ok, so stupid question time. I fill up the oil before installing the compressor, then still run the vacuum pump for an hour etc? It doesn't suck all the oil back out again?

    Charging a new A/C system

    So to be clear: In a brand new system, the total oil requirement in 10oz? With an A6 compressor, do I put it ALL in the compressor, or do I add some to other areas? I want to make sure I am clear on this part. I think I can handle getting the freon in and correct, but it seems the oil question...

    Charging a new A/C system

    Ok good idea on the oil. I may just change it to be sure. As to the warranty - here is what is weird. The box and paperwork says it has a 2 year warranty, which would be over already. However, when I go to the Advance website and look up my original order, it says that the compressor has a...

    Charging a new A/C system

    Ok, I repaired the evap box with some fiberglass and reinstalled it along with a new evaporator. Took a bit to figure out the tangs, but I think I got it. I also noticed that the tube coming out the bottom was bent to a goofy angle compared to the original, so I horsed it over to the right spot...

    Charging a new A/C system

    Again, thanks for the help guys. I guess I'll send back the Suburban line. I can't figure out a good way to plug that port. The only issue with the old line was that I had cut in an inline filter. I pressurized it with air under water and there were no leaks so I think it should be ok. I did...
