ScallopDiver 4 Posted July 28, 2015 Author Report Share Posted July 28, 2015 i will give that a try then let you know how i get on , cheers bealieboy Link to post Share on other sites
ScallopDiver 4 Posted July 28, 2015 Author Report Share Posted July 28, 2015 i have a question about the gear box in the VR now the number on the outer casing is 02a but the numbers on the inside of the casing apparently relate to a diesel gear box? does that sound right or should this be looked into in more detail?

reynolds9000 26 Posted July 28, 2015 Report Share Posted July 28, 2015 can you clarify where on the inside of the casing you're getting the number? as far as I know, 4 cylinder versions of the O2A are not compatible with VR6. as far as the clutch catching at the top of the pedal and sipping gears, the clutch needs to be bled. it can be tricky to get all the air bubbles out. with a brand new clutch and flywheel the clutch pedal should be engage very low to the floor Bealieboy 1 Link to post Share on other sites
mattvr6 133 Posted July 28, 2015 Report Share Posted July 28, 2015 (edited) U don't need to disconnect the clutch hydraulics just unbolt the slave only box that fits other than oem is v5 mk4 but that has to have the holes made bigger for the starter motor, as for it not being bleed right normally u wouldn't able me to engage the gears as the clutch don't clear.

reynolds9000 26 Posted July 28, 2015 Report Share Posted July 28, 2015 the theory behind the clutch not being properly bled is that if any air bubbles are trapped in the line, it will prevent the slave cylinder rod from returning to its "full disengaged" position. even a slight bit of air will cause problems for its clutch engagement. I always use a Motive Power Bleeder but before I had one I would reverse bleed the slave cylinder by pumping brake fluid into the nipple on the slave with an old school oil can with the hand pump on top.. the idea is to force the brake fluid into the lowest point of the system, thus pushing any trapping air out through the brake reservoir.

mattvr6 133 Posted July 28, 2015 Report Share Posted July 28, 2015 Never had that issue of air being in the system yet u can still get gears, all the clutches I've changed on a daily basis alwAys needed to be bleed to allow gears to be selected, I'd be looking into the clutch having an issue Link to post Share on other sites
reynolds9000 26 Posted July 28, 2015 Report Share Posted July 28, 2015 the symptoms of slipping clutch combined with the high pedal engagement still leads me to believe it's a hydraulic issue. assuming that the pressure plate was replaced along with the clutch and the flywheel has a fresh machined surfaced it is unlikely a brand new clutch would slip unless clutch disc has somehow glazed. it still wouldn't explain the high pedal engagement. I suspect that slave cylinder seal has torn and is allowing air to be drawn into the system with every push of the pedal. Link to post Share on other sites
VR6Pete 1,455 Posted July 28, 2015 Report Share Posted July 28, 2015 I was going to say slave seal. Quite common issue and had it with a couple of my VR's in the past. Link to post Share on other sites
ScallopDiver 4 Posted July 29, 2015 Author Report Share Posted July 29, 2015 thanks guys for all your replys, ive bled the system replaced the oil kept bleeding until nothing but oil, now the bite point is half way which i think is about right although this is only the 2nd one i have owned, i bought the silver L reg that was advertised on here.seems to be running sweet as a nut now, does need a remap though.

reynolds9000 26 Posted July 30, 2015 Report Share Posted July 30, 2015 when I did the VR6 conversion in my car I spent 3-4 hours bleeding the clutch system just to get the pedal to firm up. Glad to hear you got it sorted, or mostly sorted! Link to post Share on other sites
