my ride vt ecotec

[vt3.8lt]

hey does anyone happe to know how far onto the gide the seals will go i was looking at my old ones last night and the old ones dont seem to go on very far about a mm ish i thought maby they need to be driven on with a socet or something but i not sure?? cheers dane

[wozza]

never done a 3.8 but all the other heads Ive done over the years, they had to be tapped on till they bottomed out on the guides

[vt3.8lt]

cool thanks man thats what it looks like with these as well but there such a tight fit i didnt want to force them on if that was not the way there supposed to go

Hey guys i got the valve steam seals replaced and got it back together today with a new pcv system and this thing still isnt firing on all cylinders still still says its idling at 100kpa or more even though it clearly isnt im starting to think of different ecu options but i would rather keep this thing running a delco i think something may have gone wrong with the ecu i have so im going to try a different one and see if it makes any difference

No need for an aftermarket ecu that would be a waste of time and money. A 424 PCM from the wreckers shouldn't be expensive. Measure the MAP sensor voltage with a multi meter see what it says.

Yeah witch is y id rather keep this thing on a delco even if it means having to go to a 808 or back to a vt pcm but as far as i know it cant run a map sensor at all im gonna try another 424 n see if maby the one i got from the wreckers has a fault just to be sure as its the only real thing that has changed but ill definitely have to check the map voltage its weird the map says its at about 68-70kpa ish but the dot for the data tracing is legged on 100kpa so i dont think the map will be an issue but ill check it all the same

[Holden202T]

you got a log you can post up ?

[vt3.8lt]

Yeah one of the ones a few pages back are showing the same symptoms i can get a new one if its needed though

[festy]

I just had a quick look at your new bin.xdl log from page 16, the data tracing seems ok?

Hmmm ok thats strange it was recorded while it was pegged at 100kpa as far as i can remember this only confuses me further ill have to get another log i suppose and see if it shows the same on your computers as mine was it like that for the whole log? It shouldnt have been
