I found the problem. Broken rocker arm on the exhaust cam of that cylinder. I need one of these as soon as possible. When I get the specs from Peter, I’ll be looking for one asap. ---

Thanks for the guys who pm’d me with rockers, but I didn’t hear back from anyone for sure, so I have 8 coming express post from CA. I figure if they’re a weak point, and who knows exactly how long they’ve been in there, it’s better to protect the head and replace them all. ---

Well that’s your problem right fuckin’ there. 😛 Good to hear you figured it out, hopefully there’s no other damage. I’d do several oilchanges in a week after you swap that rocker arm out, who knows what shit got in your oil when it popped. Hate to see you spin a rod after getting this fixed (speaking from experience) ---

Nice, I figured I’d buy some walmart oil and change it a few times before going back to synthetic. Should I change the filter each time, or would it be ok for those few times I wonder? ---

Id say use the Fram a couple times than get a Nissan filter. Don’t stick with the Fram. Bad things happen that involve the filter breaking up inside and well, you get the point. To bad I hadn’t seen the “WTB” earlier. I’ve got a full set of rocker arms just sitting in my garage I would have been willing to ship out to you. ---

Depends on your wallet, if you’re not changing it every oil change, do it every second one. I’d recommend dumping at least 2 cheap changes through it in the first few hundred km, then put the good stuff back in. Since I already built a motor and found out all the crud wasn’t out and spun a fresh rod bearing, I’d say do one, idle it for a bit in the garage, drive around the block etc, work the oil all the way through, and dump it, change the filter, do 2 more over a few hundred km on that filter, then put a good filter and oil on it… That’s just my 2 pesos though, someone else might have some other suggestions, I just know I’m paranoid about that crap now 😛 ---

Oh no. That would have been ideal. I paid the price for 4 day guaranteed from California, but they were “on sale” so I got out for about $300 US ---

I don’t have an inspection or insurance yet because this happened the night I took it off the truck. And the first AutoX event will be the day after I get these. Leaves me almost having to do an oil change at the track. It’s hard to do this without having plates to cruise and work the oil through… ---

eeesh… I’d really recommend trying to get at least 1 change through it before you bring it to the track, spinning it up to 7K at the track with potential metal shavings in the motor is kinda begging for it… ---

If they get here on Thursday, I’ll change the oil before installing them, once after an idle/1km, then Friday I’m going to try to get an inspection. I’ll change it Friday night or Sat morning at the track. It really depends on when they show up here.
