fuzzwaldo 1 Posted March 19, 2015 Report Share Posted March 19, 2015 hi i bought a 6 branch from ebay but there are 2 holes on the down pipes which need to be blanked for it to be used. i have added a very poorly done picture of the holes which need to be blanked i have tried various different bolt sizes and shapes (m10, m12, bsf) but i cannot get anything which will fit. has anyone else had this problem and if they have what bolts did they use to fit it any help is appeciated thanks Link to post Share on other sites
djiceman 131 Posted March 20, 2015 Report Share Posted March 20, 2015 Yeah i've got the same issue and to be honest, i've just jammed two bolts in there that were left over after stripping my engine. They are too long so don't fit properly ut I need to go into B&Q and check the size to get shorter ones lol. Link to post Share on other sites
dave_424 48 Posted March 20, 2015 Report Share Posted March 20, 2015 The threads are M18x1.5mm Look on Ebay for "lambda sensor bung" and you will find what you're looking for Dave Bealieboy 1 Link to post Share on other sites
Sump_slammer 23 Posted March 20, 2015 Report Share Posted March 20, 2015 I dont think these are lambda bungs they were too small. Ive got a 6 branch in my garage which is not being used ill have a measure up and tell you the size. Link to post Share on other sites

fuzzwaldo 1 Posted March 20, 2015 Author Report Share Posted March 20, 2015 cheers for the replys i have tried a m12 bolt but the the threads seemed wrong even though the bolt was the right diameter. i have ordered some unf bolts 1/2 x 1 1/2, which i will cut down to the right length, as this is the only thread type i have not tried i will let you know if i have any luck cheers Link to post Share on other sites

Treva1990 17 Posted March 22, 2015 Report Share Posted March 22, 2015 Could you not take it to a local machine shop? they Will have loads of bolts and will sell you the correct ones to fit. Link to post Share on other sites

fuzzwaldo 1 Posted April 12, 2015 Author Report Share Posted April 12, 2015 I didn't realise that there were different thread m12 bolts every day is a school day Link to post Share on other sites
Sump_slammer 23 Posted April 12, 2015 Report Share Posted April 12, 2015 (edited) Every bolt can have a different pitch. Some easyer to get than others. Well good luck with the project bud Edited April 12, 2015 by Sump_slammer Link to post Share on other sites
