Technical Sheared Bolt! (through Throttle Body)

[kazer92]

Hi there fellow fiaters. first post here, been browsing this brilliant site for the last month helping me with a mk1 punto 75sx 1.1. finally got some spare time to do some maintenence work and tackle some niggling problems.

anyways, have taken the engine apart to varying degrees lately, getting familiar with the car, not doing anything silly, just taking things off, cleaning, then replacing (been trying to find source of acceleration lag at 2500rpm).

today i was putting everything back together, tightening the nuts on the 2 long bolts (maybe 15-20cm) that go through the throttle body and whatevers underneath, and one of the bolts sheared near the top
Anyone know where i can get a replacement for one of these bolts?

kept the sheared piece and put everything else back on, it looks like i would be able to run it without doing tooooo much damage, throttle body is fairly tight with the remaining bolt and the 2 plastic lug things.

waffled on a bit there i know, any help would be greatly appreciated :worship:, have googled for parts but they are rather specialised it would seem.

Scrappy, Dave in Watford (member, do a search), Big Mick at eurocarcare in Derby (Google will find). Same part on early Sei 1108 and Cinq Sporting. Pretty sure you'll have a monumental air leak if you just use one bolt.

thanks very much guys, will do a bit of digging.

after experimenting with it running in my driveway the other day, i am definitely getting an air leak somewhere after the throttle body. revs are higher at idle, and when i push down on top of it all (air intake etc.) the revs drop back down to what idle used to be. there is also a very high pitched whistle noise (air getting sucked in) when foot is off the throttle.

took it for a spin this afternoon after cleaning the lambda sensor (unrelated), actually ran really smooth, with no spluttering or acceleration lag i was trying to fix initially, but still with the whistling noise that gets louder and louder the longer the engine runs. sitting in any traffic is quite embarrassing haha.

obviously my fuel consumption is going to rise considerably, as well as the risk of unfiltered air into the engine, but not a fatal concern? but will definitely have to do something about it soon.

thanks again for the help
