DamirGTI 344 Posted August 20, 2007 Hello ! I've been reading "Erling-s" tightening instructions for cylinder head which cames with the gasket , and for some reason i misread something which was written on the bottom of the page regarding head bolts/washers oiling .. It says : 1- Lightly lubricate the thread and the bolt seal . 2- If the bolt has been installed with a washer , oil the gap between the washer and the bolt head . *Important : Never oil the washer surface that makes contact with the cylinder head . However I've done this bolt washer oiling on both sides Can somebody explain me why is important not to oil the washer surface on the bottom side which contacts the cylinder head ?! what can go wrong if it's oiled on both sides ?! Thanks ! Damir Share this post Link to post Share on other sites
Richie-Van-GTi 74 2 Cars Posted August 20, 2007 it needs a dry face to ensure maximum friction to minimise risk of it working loose. TBH Ive fitted a few heads that have been oily and would no doubt of had oil on both surfaces, never had any issues with them. Dont worry about it, just stick an extra 10 degrees on final torque if you want to be double sure. Share this post Link to post Share on other sites
Sandy 191 Posted August 20, 2007 You'll break the time/space continuum. Or perhaps to stop the washer rotating in the seat. Share this post Link to post Share on other sites
DamirGTI 344 Posted August 20, 2007 Hi ! So it's not something serious to worry about , i will just check if all the bolts are tight enough Thanks ! Damir Share this post Link to post Share on other sites
Stonesie 0 Posted August 20, 2007 *Important : Never oil the washer surface that makes contact with the cylinder head . I dunno why thats an issue, theres loads of cars out there that have no washer, just an enlarged bolt head that needs to be oiled... That causes no problems.
