Title: Leaking TIAL MVR Wastegate Post by: aef on August 23, 2016, 10:36:04 PM Hi,
does someone know how often this happens? I found some videos on yt with "tial leaking" and so on. The problem is that we can not sort out the boost while its leaking. Ther is currently a 0,8bar = 11,6 psi spring in it but because its leaking its not opening at 1,3/19psi :( With a little bit of aluminium/copper paste its is not leaking. Looks like the O-Ring is no spare part. The air is definately coming from the O-Ring and the connection between the milled alloy head of the tial. This part is not old and has not seen this much km/miles and Egt wasnt hotter than 950 degree celsius. regards Title: Re: Leaking TIAL MVR Wastegate Post by: Jim_Coupe on November 23, 2016, 04:16:03 PM I have been running 3 if them but havent noticed any leaks in the diahpram. But i had one with bad valve seat.. found replacement for that.
