Gtr Bovs Maintenance

[SiR_RB]

I just want to know if the stock GTR blow off valves can be removed and cleaned and also checked to make sure the pistons are opening and closing properly?

I'm still experiencing lag/hesitation for about a second or so when shifting hard and fast so I thought i would check to make sure my bovs are opening properly and then go from there.

Thanks

even with the new profec b?

[SiR_RB]

Yep but I've only put the new unit in so far, haven't been able to put the new solenoid in cos of the rain

[DVS JEZ]

spewin, its only really happened since you pulled off nd cleaned all your cooler pipes and cooler etc, is that right?

did you remove the BOV's then? you can try mine if you want

When it lags I get peak boost of 24psi for some reason?

Also gotta check that the vacuum hose going to the profec b through the firewall isn't kinked, i'l do this and change the solenoid tomoz and see how it goes

[SiR_RB]

Yeh seems to have done it since then but could be a coincidence

I didn't remove my bov's but I made sure all the clamps on it were tight

[SiR_RB]

So is there anything I can do to service my bovs? Anything inside I can clean or inspect etc ?

Did you have a look at the nissan manual?

Pull tham off, give them a clean, check they arent siezed, and vac test the diaphrams, there isnt much else that can go wrong with them.

a quick dyno run with boost logging will tell you where the issues is (BOVs/wastegate/boost drop etc)
