Noticed this mod on Engine. HELP.


Wipeout

Recommended Posts

As i thought, Scooter was unaware of this mod. Anyway, im still not convinced i have successfully restored it to sequential setup. The actuator does move in and out with engine revs but it is'nt alot and i did rev it high. Can anyone local to Fareham help?? Or does someone have a detailed list of things to check, test or look out for. Thanks again!!!

i hope you get this sorted Chris. Now you 'Know where I live' so to speak i may as well come clean on a couple of points i would omitt from my sales patter :D

I have run at pod and it did respectable standard car times, so i don't think theres any problem with the cars power, so should hopefully be a relatively simple hose VSV problem.

 

Bobbeh if only i'd whacked it on the rolling road in Alyesbury way back!

Thing is the guy i got the car from had had it for +2 years, and he just wasn't the modding type AT ALL, he'd had the major cambelt service done at McCarthys Toyota (where i'm sure it would have got a test drive) and also i'd had a oil leak repair (+general check over) done at Leon's,maybe it's not that noticeable unless you step from one to the other:conf:

 

I'm still finding it mildly amusing / annoying that i've never experienced the normal setup.

No worrys Scooter, I will endever to get it sorted today so you can have a go tommorrow :) . If anything it will be another pipe linked out that i have'nt found yet. I bought a new set of IK22's from Alex H and they arrived today so i will fit them and see how it goes. Have fun!!!

I have a similar problem on my UK spec which had the TTC mod already done.

I have replaced all pipe work on x2 VSV to normal and after a few checks it looks as if the actuator doesn't move!!

 

Is there any pointers as to where the actuators may have been wired/wedged open?

When it says 'wired' open, it literally mean with a bit of wire. You should be able to see it wound round the arm holding the butterfly valve open.

 

On my bottom actuator (exhaust valve) I disconnected the actuator arm and locked open the valve. With the top on I had a spare pipe and completely removed the butterfly valve.

That makes sense now :stupid:

 

On inspection there is nothing wired/wedged to hold the arm open.

 

Is there anything else I should check for?

I will test the pressure tank tommorow to see if that could be causing the problem.

 

thanks for the replies :thumbs:
