OOHPS!!! Wrong plugs

[Targa Tom]

Had an iridium plug lose itself on the weekend.... no Zero compession on #6.

I seems the exhaust valves are open (burnt or plug bits).

Are Rb20DET heads bucket and shims or hydraulic??

Whats a good price to pay for a head gasket?? and can you buy valves in OZ?

What is normal valve clearance for In & Ex.?

Any help with these questions appreciated.

Regards

PS Next Track day will run Heat range 9 plugs!!!

I recently burnt 2 valves in number 6, see thread:

My valves were sourced from Nissan in melbourne, you may have to ring around to find some. Ideally ring your local nissan dealer and they should be able to chase them down for you. If not you will have to wait to get them from Japan (might be a weeks wait to come via air freight).

They were 55 dollars each.

RB20 heads use hydraulic lifters (i remember listening to mine after they put the motor back together, ticking away for a good 15 minutes until they pumped up).

Gasket kit was more expensive, cant remember exactly and ive since misplaced the receipt, but i believe it was around the 220-250 mark.

Mine was cause after it ingested an electrode off a plug due to excessive detonation running high boost on a stock cooler. Ive since found that the aftermarket management is leaning out the fuel mixture quite badly on higher boost settings (combination of many factors including, Aussie fuel and weather).

I hope you get your car back on the road quickly
