[QUOTE="Raja_Mongkut, post: 629571, member: 7413"] Finally gotabout to replacing that damned air slide valve [ATTACH=CONFIG]26280[/ATTACH] Old vs the not-so-old [ATTACH=CONFIG]26281[/ATTACH] Removed air filter and throttle body to gain slightly more access to that damned part. finally replaced after 1 hour of wrestling in the dark - wrench in one hand, torch in the other. After reconnecting everything and triple checking all vacuum hose, started her up. Choke, gasp and gargle, she dies after 2.4 seconds. Panic ensues. check vacuum lines and connections again. same scenario happens. Then i notice this: [ATTACH=CONFIG]26282[/ATTACH] A crack all around the brake booster non-return valve. The part looked like it was gonna crumble apart anyway, and while fumbling in the engine bay i must've bumped into it on couple occasions, hence cracking the top. Nothing a lil epoxy can't seal. Mix up a solution and apply generously around the long crack. 1 hr later started it up, still hesitated abit so i mixed up another batch of epoxy and added a double layer. Note that this was at 2AM. Due to the previously faulty air slide valve, maximum air had been allowed in via that valve, and the idle screw on throttle body was turned all the way in to reduce the air intake. Now with a functioning air slide valve, more had to be introduced to prevent the engine from stalling. Adjust the idle to 900rpm. Perfect. Previously it was running at 1.2k rpm. Great, i deserve some rest. Drove it to work this morning, epoxy seems to be holding fine, but i'd like to get it replaced anyhow. A project for another day yet again... [/QUOTE]
