plugs are good maybe 4000ks old still should be fine they are the correct heat range.
oil lvl is fine but does need to be changed which will be done this weekend.
radiator lvl is fine and i have replaced the cap.
not sure about oil pressure, don't have a gauge.
doubt it would be a headgasket, coolant seems fine, but ill check the oil for water when i change it this weekend.
could be the water pump but when i have the cap off and give it a rev you can see the water moving, and it looks like its moving alot faster than my mates rb20 whos water pump is only 30000ks old....
i reckon ill have to swap the radiator and thermostat and go from there, dont really want to do the water pump looks like a big job.
what do people think of those cheap china radiators, ISC sells them for $299

i figure its going to cost close to $200 to get mine flushed and tanks replaced so may as well go new?
