4-ac - Rattle At High Revs

Yes, tappet info would be much appreciated TRD ke70. I'm running thicker oil and its not helping though they are quieter than they used to be.

 

Fire away!!

Thanks heaps man. I'll set it all up tomorrow or thursday and see how i go.

[mikeys toy[RL]]

my experience, 4ac's like to drop valve seats

[blown 5k]

Wouldnt hurt to get a surface grind if your doing a headgasket to ensure the head is perfectly flat sometime a blown headgasket will form a little "track" where its blown and if its not corrected it`ll just blow again.008" inlet and .012" hot just in case you havent got metric feeler gauges :) .

i got a set of both, but thanks for that. head gasket is fine on this engine, no bubbles in the radiator, no milkshakes in the sump. :jamie:

 

thanks again people. much appreciated.

Adjusted valves, didn't have a manual, so i was guessing it goes:

 

inlet-exhaust-exhaust-inlet-inlet-exhaust-exhaust-inlet

 

Is that correct?

 

Cos the bastard now won't idle, and it's decided it wanted to run on 4, then 3, and now 2 cylinders.

Fixed. After a lot of rooting around checking and re-checking valves clearances (which i'll hafta do again tomorrow) i decided to whip the weber off.

 

To my suprise (well, not really, i suspected it), the Lynx adaptor plate to the manifold had blown half the friggin gasket apart.

 

Nothing a tube of Silastic can't fix :jamie:

 

Thanks heaps for your help TRD ke70 and ROL-010?? i think. Much appreciated.

 

Though i did snap off a spark plug. Will fix that tomorrow.
