Head weeping

[greenlandy]

So after sorting out the loom once and for all (fingers crossed)
rdlccrazy.proboards.com/index.cgi?board=hybridchat&action=display&thread=8489
the head has started to weep again... it stops after the engine has warmed up. This is the second quality gasket I've tryed do I go for a OEM one or ship the head and barrels off for an assessment? If so who.
Thanks in advance for any help

Have you re-torqued the head after first heat cycle? You could re-torque it a touch higher and see if it cures.

Are your bores much over size? If they are your head gasket bore might be a bit on the small side.

You could try a touch of sealant.

Genuine head gasket may do the trick but a good quality pattern one should be ok.

I would try those before paying someone to look at them.

Failing that, ensure head is flat and both barrels th same height.

Yeah re-torqued head was thinking of doing it again just as a last resort. Bores are 1mm over. Head seems to be flat not got an engineers surface plate to check for certain though. Used Norbo's Quality ones was wondering if a copper one would do the trick?

I checked my head on the living room window for warpage before lol

i used a genuine gasket and it weeped on front edge in middle

took it back off n put a "smidgin" of sealer on...sorted

Try re-torquing the head before you do anything else, mine started blowing coolant out the expansion bottle second time out, re-torqued and was ok for a few rides then did it again after a severe thrashing. Re-torqued a bit higher & it's been fine for the last year

I'm away this week but will warm her up and retorque later in the week. If it leaks again I might resort to sealant but have never needed to on any other engine.
Can you O'ring a 4L1? If so how much?
On another note at what age does a bike have to have indicators? Thinking of throwing it into an MOT if I can later this week.
