... and 20V (including BT) doesn't have VVTi. Its only plain VVT.

You are right;but my point was(both VVT and VVTi) depends on the oil pressure to activate its mechanism and 7af conversions should use Bt oil pump.Just wondered if anyone used a high cam with VVT and how it performed.

wah.. this racun kuat kuat one..... sifu 2o2r,

got a noob question to ask u lah.. coz my 7A fe wanna kahwin with my 4a GE liao.. what is the reccomended gasket ar? i will be using bt piston with bt head.... according to bro howard, he is using 0.5mm get around 12 for compression, but it is too high to be driven smoothly, i prefer to go back to standard bt compression of around 11 to 11.5
is 0.7 ok? or 1mm? i know there is a way to claculate but i couldnt find it so have to ask u sifu loh...

another noob question, northern got ppl do engine balancing? it got around how much?

bro.. your 7A want to kahwin to 16v or 20v? i can offer some practical ideas as we have tried numerous times. 16v and 20v got big differences in our experience...

Anybody have standard VVT intake cam pulley for BT? Mine already broken. sound really noisy. Asked Kenny earlier but he said no stock... anyone please?

 

[pcmoddingmy]

I think I might have one back in Ipoh, but chopshops should have them as well. But I heard after changing to used VVT pulley, the sound will come back in 2-3 months or earlier. There's a foreman who can rebuild VVT pulley for about RM500 or you can also PM sifu chinozie.

 

[hon_cs]

wow dint know rebuild cost so much. then how much for chop shop pulley?

AE100PRO, looks like ur engine is in bad condition. I suspect piston rings worn out and maybe damaged piston or piston cylinder. Looks like the engine is due for a complete overhaul. If you plan to drive the car still, make sure engine oil level is always enough (check daily). Else, more parts will be damaged due to lack of engine oil.

Btw, have you tried to open up the engine oil cap? You should see some smoke coming out from there too.

 

[cybtech]

AE100PRO, when you're really ready to do something about your problem, go to any of your preferred 4AGE 20 master foreman shop, tell them to take your top set off to check your valve and piston conditions. Yes from there you may check the conditions without take the whole engine off.
So if only your Valve gone bad... just do top overhaul,
and if your piston gone case.... do a full overhaul.

Mine engine also has smoke problems and always refill engine 1liter oil every 2000-3000KM

after took to shop, they said only valve seals problem, and i verified it myself.
