Reinz Cylinder Head Bolts, FAI Gasket
How'do folks
I'm ready to order my last couple of parts needed for fitting my new Cylinder Head etc.. I will be fitting New Head Bolts I can source Victor Reinz Head Bolts locally - and an FAI Head Gasket Can anyone confirm the tensile rating of the Reinz Head Bolts ? I'd prefer to fit standard 9.8 (tensile) bolts - and an Elastomer Gasket (with standard oil rail) are the Higher tensile bolts 10.9 intended to be used with the MLS Gasket and upgraded Oil Rail ? so many options available - I just want to be sure of what i fit and compatibility of parts. any opinions on the FAI Head Gasket ? (i'd prefer to source this locally - I don't want to receive another Kinked Gasket in the post) it's a subject covered many times i know - I've been searching too long and none the wiser r.e these questions Paul. |

As to the head gasket, Federal Mogul "Payen" BW750 is the best option Brian |

cheers Brian the reason for changing the bolts is to be sure what i'm fitting - the bolts have been changed for HGF repair in my ownership - not by myself tho, and i can't remember for sure what brand/spec bolts were purchased. that said - you have me thinking about re-using the bolts there are no apparent issues with the sealing of the Head/Block currently - so no suggestion of clamping force issues with the currently installed bolts I'd still like to clarify this - are the Higher tensile bolts 10.9 intended to be used with the MLS Gasket and upgraded Oil Rail ? or can they be used with an Elastomer Gasket and Standard Oil Rail ? and, would bolts be marked for Tensile rating ? the reason i ask is - I know i ordered my Currently fitted Bolts from Mat (DMGRS) and from what i Can see Mat only has the 10.9 rated bolts available. if the higher rated bolts are compatible with the Elastomer Gasket/Standard Oil Rail set-up - and 10.9 spec bolts are what is currently fitted - that's fine for me as long as i know for sure of course i'd need to know which bolts i Have for the Angular torque variance.

the more i read the less informed i feel r.e spec/compatibility of bolts Gaskets - and Angular Torque specs
i.e - the use of Elastomer Gasket with 10.9 spec bolts - from what i can make sense of it = the Higher tensile 10.9 spec bolts where intended for use with the MLS Gasket ? and the Angular Torque specs are specific to the use of these Bolts with MLS Gasket and Upgraded Oil Rail ? So - Using the 10.9 bolts and revised angular torque spec with the Elastomer Gasket should be incompatible ? I know folks have fitted the Elastomer Gasket with 10.9 bolts - I may have this in my car currently. I'm swaying back to my initial preference of Kamax 9.8 bolts - for peace of mind when fitting the new Cylinder Head - with Elastomer Gasket = 20nm followed by 2 x 180 degree rotations (4x 90 degrees ) and I know I'm using the intended specs/parts *to add - other info i've just seen suggests the revised Angular Torque procedure 20nmx180x135 degrees is specific to the use of the MLS type Gasket WITHOUT the Head Saver Shim (is this the N-type? Gasket) so not specific to the bolts tensile rating ? Paul. Last edited by Sheraton; 10th August 2018 at 15:25.. Reason: update |

So r.e torque - would it be correct to assume 10.9 rated bolts with Elastomer Gasket should be 20nmx180x180 degrees(0r 4x90 degrees ) - 10.9 bolts with MLS (+ Head saver Shim) and Uprated Oil Rail should be the same 20nmx180x180 - and only the N-series(?) MLS Gasket (without the saver shim) and uprated Oil Rail should have the revised 20nmx180x135 torque spec ? I've sourced a supplier for a Payen BW750 Gasket and Payen HBS005 Head Bolts - at a Good price - I figure that i can't go wrong with this combo - although the supplier doesn't list the 75 as compatible, so i have to wait for them to confirm my reg number before ordering....lol... I missed office hours today so should be Monday before i can order them I've probably been overthinking this one It's nice to know which end is which and why when possible. I'll do these bolts 20nmx180x180 Paul. Paul. |
