  4. Re routed catch can now I'm getting blue smoke

    in Engine Tech And Modification

    Posted

    Hello everyone.For a while now I have been wondering why I was catching so much oil in my catch can turned out I had it set up wrong. I had the passenger side(fresh air) and the driver side connected to a T fitting that hooked up into the IN part of the catch can. The clean air was correct it is hooked up to the top of the manifold and to the OUT side of catch can.

    What I did was drill a hole in my intake tube put a fitting in it, sealed with rtv and hooked it up to the passenger side head, simply removed the t fitting and kept the driver side hooked up to the IN part of the catch can.

    Since then my truck has had a constant blue smoke. Only at idle once I'm driving it goes away. Did I do this wrong? I followed the instructions off the TBSS manifold swap in our forum. I have the tbss mani on my Lq4 and that's how he set his up.

    I heard blue smoke is bad, valve seals, guides or piston rings. But my engine is rebuilt everything is new only 3.4k miles on the new motor. Has milled heads,cam etc. This blue smoke can't be cause by O2 sensors can it? Sam Miller tuned it, said b1 s1 and b2 s1 aren't working properly, I replaced them before the blue smoke and they still don't show up on his computer so my truck will die when I come to an abrupt stop due to 1 sensor sending too much fuel to one side. I always thought the blue smoke was gas since it smells like it and burns my eyes and nose. Any who does anyone know what it could be? It had blue smoke every now and then on start up just like the first 2 seconds then go away and now it's only at idle.

     

    Any help/suggestions will be greatly appreciated.

  5. 799 heads milled .040 What gasket should i use?

    Hey guys i just bought a pair of 799 heads from KHP yesterday.

    He recommended i mill them .040 to bump my compression even further than just a simple head swap from the 317s and use a stock GM gasket on my LQ4, like a dumb ass i forgot to ask if it would affect my PTV clearance with the cam im about to put in.

    Its a custom grind 231/239 .617.623 114 lsa anyone run a similar cam and or setup? figured i'd ask you knowledgeable fellows

    Hey everyone. I know this has been covered countless of times but I thought it would be better if I get direct answers to my questions from you gentlemen.

     

    My truck as it sits has

    Pacesetter lts

    Volant CAI

    3 inch exhaust straight pipes

    4.10s and a KHP Tune.

    Khp recomended a 231/239 comp cam for the engine only problem is I'm kind of working my way up.

    Im planning on taking it to them a couple of days before my b day to get the cam 3600 stall and tranny cooler to get the most out of the cam. My only main question is,how aggressive is the cam? I see a lot of guys running 224s and 228s any big differences between those and the 231? She's my daily driver not looking for a full on race truck just a fast slab for the street!i want people to pull up next to me and wet there ****ing panties. main goal is at least 400hp.

    My second problem is the heads I can get 243s from them as well real cheap to. Only thing is I plan on slapping a procharger later on but I mean like a year or 2 I want to be N/A for a bit. Should I leave the 317s to keep the lower compression or get some 243s? Or 317s with different gaskets?

    Last question being about a month after the cam I want to get a FAST 102 manifold. Will my stock TB work? It's drive by wire and their 102 throttle bodies that I've seen are drive by cable.

    Thanks ahead of time!

  16. LQ4 Acting Weird :(

    Have you pulled the plugs on that side. Lots of things to trouble shoot. Clogged cats. Fuel pump. Broken plug.

    Fuel pump went bad about 3 months ago put a brand new one in. As for cats well I don't have any,straight pipe and MagnaFlow mufflers.

    And yea I pulled all the plugs out both sides

    Mine did the same thing a few months back. #7 coil pack went bad.

    Is there a way to check them?

    Hello everyone hope you all had a good new years, and an alright hangover recovery.

     

    Well my beast let me down 2 days ago hopefully you guys can help me out a bit.

     

    It started with a random misfire, Didn't throw any codes no flashing or check engine light. Later that day on my way home I gave it a little gas. Sounded bad it misfired a lot check engine light flashed didn't stay on. Last time it did this it was a loose spark plug so I checked them all found 1 was a little loose tightened it started it.

     

    Started up a little weird engine light was on had a weird/rough idle to it. These are the codes it threw. p0171 p0174 and a p0300

    I can honestly say it cant be my 02 sensors I just changed them and the other 2 are deleted with my tune along with the EGR. I haven't had a chance to clean the MAF, which I will do here in a bit its just too ****ing cold outside atm LOL. In case it isn't something simple what do you guys think it could be?

    Also it started to have a knock on the passenger side of the engine sounds weird, tripping me out it started after I fixed the plugs. It didn't get this bad until after I re tightened the plugs. Although my header gasket on that side does have a slight exhaust leak it could be it sounds that way because of the misfire.

     

    Thanks ahead of time!

  20. Truck revving high at 60mph after engine swap

    in AWD, Differential, & Transmission Tech

    Hey guys I just got my baby back from the shop did a 4.3 to 6.0 swap right off the bat I put a corvette servo in and that was it at 60 mph she is at 2500 rpm which is way too high when I had the v6 in at 60 she was churning 1500 rpms.

    I took it to the tranny guy he said the tranny is fine cause it seemed like she wasnt going into overdrive. He said it could be the gear ratio which I found out are 3.55s anyone knkw what it could be? Or is that just the way it is?

    Thanks ahead of time!
