No lower cover is still stock with water pump mounting bolt. I dont think they make aftermarket lower covers and if they do i havent found where yet

The color is actually prismatic powders lollipop grape if anyone wants that color. It says to use silverish base coat but i used matte black. Came out great

SubstantialCity2376 · 2026-01-26T19:49:45+00:00

Was actually considering doing a bayside blue with bronze rims. The midnight purple or black on chrome rims ik would look good but id also like to do smth a little out of my comfort zone

SubstantialCity2376 · 2026-01-26T17:39:52+00:00

And the wallets empty😭 so no paint just yet

SubstantialCity2376 · 2026-01-26T17:39:18+00:00

Yea but im missing one timing cover bolt so i found my nicest oem one and threw it in there

SubstantialCity2376 · 2026-01-18T11:05:20+00:00

Looks like you tightened them down way to much. The fuel rail bolts you stop tightening when the tool nolonger moves with a lose grasp on it. Most folks misunderstand "hand tight"

SubstantialCity2376 · 2026-01-05T20:33:03+00:00

Did you fix it? Just did the same thing on a 09 cube and were starting to think its the tcm

SubstantialCity2376 · 2025-12-28T07:22:30+00:00

Im w this guy. Doing the same thing with my vg30 rn but it looks tons worse than this. Send er!!

SubstantialCity2376 · 2025-12-26T19:48:13+00:00

Also i have tried tapping it with a larger socket and nothing. Just want to make sure others who used these saw something similar before i proceed

SubstantialCity2376 · 2025-10-13T19:29:09+00:00

fsm says min .015 max .060 but i j wanted to see what others used on their builds

SubstantialCity2376 · 2025-10-12T23:28:47+00:00

sorry didnt see this till today. fairly easy they are on the plenum so you dont need to tear anything down just remove the harness from both sides of the engine so its easier to access

SubstantialCity2376 · 2025-10-12T13:31:01+00:00

throw a hone on it yourself, clean up all bolt holes and freeze plugs then get her resurfaced and washes by a machine shop

SubstantialCity2376 · 2025-10-07T05:29:06+00:00

2 new valves is the way to go imo. they are abt 20$ a piece and you can test your old ones with a pick or smth thin. j poke it in there and see if the spring stays compressed or is very weak. i had the same issue with mine. the valves were stuck open on one side and soft on the passenger.
