Default What's the trick to getting the valvecovers off...

... with the engine still in the car? Those last few bolts on both sides are not accessable. Do I loosen the engine mounts and tilt the engine? Loosen the brake booster on the drivers side? I'm sure some body has the secret.
I'm finally getting down to installing the ported intake and want to repaint the valve covers.

Thanks
H

on the driver's side you need to loosen the brake booster. this is done under the dash and it is much easier if you remove the driver's seat. it is a bit of a PIA to do, but many have done it.

I removed the Brake Booster and I also remove the Heater box piece ( the smaller) one covering the Cam cover..

careful on those Torx Bolts

now I need to refinish the covers

Start about half way down.

Cool... thanks... Can you get away with just loosening the brake booster or does it have to come all the way out?

well for ease of getting to the bolts, better to remove it,

remove the nuts on the inside and slide the booster forward a bit. it doesn't need to be removed from the engine bay. this is what i did on mine.

You can do it with out removing it all the way. It will get tight but you can maneuver around it.

That's what I love about this forum and ZR-1 folks in general. Ask a question, get a straight answer in short order.

Thanks guys!

Stop playing games, just yank the motor, it's faster.
