When I look at the chiltons manual it says piston ring gap .004-.012.

Am I looking at something wrong here the maximum on chiltons seems to be the minimum for LCE, any insight would be greatly appreciated!]]> 2 Sat, 02 Mar 2024 12:32:53 +0000 https://toyotaminis.com/forum/threads/locktite-on-head-studs.30637/ https://toyotaminis.com/forum/threads/locktite-on-head-studs.30637/ invalid@example.com (fred heath) fred heath I plan to replace all manifold bolts ( intake & exhaust) with studs. Stainless on intake manifold, steel on exhaust.

I’ve received conflicting advice on using something like locktite blue on the threaded portion that goes into the aluminum head. I’ve always used vibratite anti seize in the past on the bolt threads.

Just curious what other members are doing.

Has anybody dealt with a similar situation, and if so what was your solution? Is there another year's parking brake cable that's a bit longer that I can swap in?]]> 9 Thu, 17 Aug 2023 21:36:43 +0000 https://toyotaminis.com/forum/threads/1-ton-axle-rebuild.30090/ https://toyotaminis.com/forum/threads/1-ton-axle-rebuild.30090/ invalid@example.com (Olds77421) Olds77421

I've been doing some EFI tuning and recently put one on mine to find it is dancing a little bit. I'm wondering if this is normal for the engine or if I should go down a rabbit hole trying to troubleshoot?

1. Does anyone have a total timing spec for a 20R? I know the factory spec is 8* BTDC at idle (850 RPM) but what is everyone running for total timing? I'd guess it's around 28-32* BTDC @ 3000 RPM but cant find any info anywhere else online.

Tried starting up my truck the other day after like 4 months (I know, I know). Well the darn fuel pump decided it doesn't want to go anymore, whereas I used to hear it before starting the truck. It wanted to start with starter fluid so I guess my only issue is fuel delivery.

While driving the truck yesterday, I attempted to downshift into 2nd while turning into a parking lot and I had no 2nd gear! Well, that's not totally accurate. I could not find 2nd gear (I'm sure it's in there somewhere). Upon further (immediate) investigation, I found that 1st gear could not be found either. I managed to get the truck up the hill from nearly a stop in 3rd gear and parked it, at...
