Can someone give me the correct torque specs on the 20 cam cap bolts on a b17 engine, or give me a link to a site where i can find out. Thanks.

 

9 ft/lbs. for the bolts that require the 10mm socket (outer most bolts), 19 ft/lbs. for the 12mm bolts.. Latez

 

I agree with the above post. 8-10 on the 10mms and 18-20 on the 12mms,
this is the accepted range on B series VTEC models.

 

ok thanks guys

 

They're not all the same! they have different specs for the diff B series..get the honda service manual from the dealer if you didnt believe those specs i gave you before(might find it online) for the 92 GSR and you'll see..the big bolts suppose to be 16lbs but you could probably tighten it to 20lbs and be fine but that's a chance i wouldnt take cause it's possible you could snap a cam if you tighten them too much.

Oh really try torquing the 6mm (10mm head) bolts to 16lbs.. Good Luck

 

Dude.... now this is what you said.... you said torque the "big 10mm suppose to be 16lbs but you could probably tighten it to 20lbs and be fine" There are two ways to measure the size of the bolts... by the head or by the thread.... What you just said about the 10mm bolts only has one way to be taken and that is that you are talking about the little bolts that have a 6mm thread and a 10mm head... I couldn't have taken that, as you were talking about the "big" bolts because they have an 8mm thread and a 12mm head and should be torqued to 19lbs... Now i realize that you correct torque in your second post being 96in/lbs. (8 ft/lbs) but the first at 16lbs. did not make sense.... I do 9/19 but as MikeSarr_GSR said 8-10 is fine and 18-20 is fine..

oh man,i o you an apology.that's a big mistake on my part.i dont know where the fuc i came up with 10mm where i got that is beyond me but anyway,i told the author the correct specs for the correct size bolts on an earlier thread https://honda-tech.com/zerothread?id=369164 those are the correct spec's for a B17.you said you do 9/19 which is fine for the later gsr Bs but would be a little to tight for a 92 B17,at least according to honda,which B series do you have?......again sorry for the fuc up up above

 

I had the same question today and called the Acura service deps due to the lack of consensus here, The correct spec is:

8mm(12mm head): 22 N-m (2.2 kg-m 16 lb-ft)


6mm(10mm head): 11 N-m (1.1 kg-m 8 lb-ft)
