So I took the heat shield off of the exhaust manifold and noticed two bolts missing from the manifold that bolt it to the motor? How vital are these two bolts and how easy is it to get replacements? Thanks

Might be a reason why the studs are not there like they broke and were never removed.

Just depends which ones they are.:jessica:

Without them, you could get a manifold exhaust leak. You can easily get replacements (likely a stud and nut) from your local Toyota dealer.

They are missing, not broken off. They are the back two closest to the firewall. Would my local parts store carry them?

M10x1.25 studs your local autoparts might or might not have them :jessica:

Thanks all! I figured they were important! So with these two bolts missing how does it affect my truck? Sorry still a noob!

Well I sounds like they are exhaust manifold studs so their job is to evenly press the manifold tightly to the cylinder head. By doing this your exhaust will seal and not leak and also head and manifold will resist warping by having the even pressure.

Without the bolts you risk at the least a exhaust leak.

would that cause weird sound? Hard to explain, but I am wondering if by missing these two bolts, it might be causing a sound? I could just be paranoid as well

Exhaust leaks make a fast ticking sound.

Do you have a hardware store in your town? I have a locally owned store that stocks A LOT of bolts/studs/nuts/washers/ETC. I got all 8, high quality studs for my exhaust from them for a good price. Definitely cheaper than the dealership. Also, the NAPAs and Oreilley's in my area dont seem to like to stock much parts for older Yotas...so...

Even Lowes or Home Depot will have the studs. But I like to support local businesses, even if they are a little more expensive.

RobertIII

nope, just have autozone and homedepot. I checked autozone already and they don't have them. I may check home depot tomorrow. I know I am looking for M10x1.25, but what length am I looking for?

toyota4x4907

I want to say they were 40 or 50 mm... about a 1 1/2"-2"

RobertIII

K, Thanks

RobertIII

Does anyone have a part number for these? The local dealer has no clue? Also anywhere I can order them online?

Are the workers at the Dealership computer illiterate? Are they not able to look up an engine schematic for a '94 Toyota Truck 22RE?

RobertIII

They are idiots! I asked for the specs of the item and they couldn't tell me a size or length etc. This was over the phone, so I imagine its going to be fun when I go down there

toyota4x4907

Wow. Hopefully in person they can do a better job. I feel lucky. My dealership rocks >.>

Also, I measured some old studs last night that were in my garage. They are about 1 13/16" or 45mm in length....
