SignUp Now!Idk man... But I missed 2 car shows n a Dyno day. The intention was to give all this 2 weeks n be ready for the new year... Look where we r at now...lol.... It also had a rattle upon startup for a split second , cold startup, which is one of the reasons why we replaced all the chains n guides n all the timing components.
Good find! Like torspd said leave it to Ray....
Mine also has a knock on cold start for a couple of seconds then goes away. My dirt bikes would do the same with a forged piston which was normal so I am hoping the same applies... What does worry me though is it's really strange but if I start the truck and let it idle after about 5 min it knocks like mad until I give it some throttle and up the oil pressure.... or if I shit it down and restart it's gone.... Never happens when it's fully warm or if I drive it before it starts to knock it doesn't happen.... I am thinking its gotta be something in the VVTI...:dontknow:
OK, WB, let's set a 'Test and Tune' night at PBIR real soon!!
engine bay is looking awesome man! i have to agree with everyone though....need to see this thing go down the 1/4 mile! maybe get some light 15" or 16" wheels with some slicks....
If it lasts for a couple of seconds on a cold start it is most likely dry bearing knock. The clearance on the engine bearings might be on the high side of tolerance. You can get the dry bearing knock on a cold start until the oil pressure comes up and floats the bearings.
If the knock continues for a while until things heat up it might be piston slap. This is common with forged pistons.
If it continues after warm up, something is very wrong.

Ahh ok. Make sense now. But spacers are still scary. Especiay using 1/2in thick.
Just keep an eye on the spacers. I seen disaster happen with them.
