Do you mean the plastic valve cover garnish from the Lotus?  

Nope not the Lotus plastic cover. The 10 10mm bolts that bolt the valve cover itself to the cylinder head. I'm guessing I can replace it with bolts from the hardware store (grade 8?).

Similarly, I also want to replace teh bolt that holds the ignition coil boot to valve cover. My 2zz-ge didn't have the Lotus cover so the bolts look a lil rusty and water gets on top (and inside the spark plug cylinder I would imagine)

I would just order them from the dealer reason being that the threads are soft and although you might find something at a hardware store you can easily strip them because the pitch is slightly off. Also be carful with tightening the bolts as they just need to be snug and it’s easy to strip as I have on one of them by going too far.  

Its important to get some sort of valve cover garnish because it is the source of misfires when water is allowed to drip into the spark plug wells. This makes the plugs run cooler which is not ideal.

Yep, I was leaning that way. I just couldn't find it online. Maybe I'll give the dealer a call. Closest one is about 20-30 mins away. I was considering getting some ARP bolts since they make good parts usually. But with aluminum, it might make more sense to go OEM specific.

Absolutely on the garnish. It's on my list for bringing the car back to life.

The devil is in the details always. At one time I had to replace an electric water pump on a BMW and the soft aluminum bolts cannot be reused or substituted with steel otherwise it would cause corrosion and some kind of failure.

in regards to ARP bolts It’s a fallacy of thinking they are better bolts than the OEM for being stronger. In some cases the ARP bolts has caused people unforeseen issues and at best no advantage over OEM. Unless there is a situation where bolts fail then you entertain stronger bolts but some how the industry sells us on this marketing nonsense. 

I had been thinking of replacing these bolts with some anodized aluminum, simply for aesthetic value.  What say you about this, Dev?

I remember there were selling some kind of bolt dress up bolt kit a good while back. If it is specked out for the valve cover I don't see why it wouldn't work as long as it gives you enough torque to close up the valve cover so it doesn't leak. 

The last time I removed my valve cover I used a electronic torque wrench on the bolts just because the threads are fragile and its amazing how little tightening was required. I trusted the torque value and it all worked out. I even forgot to add a little dabs of sealant on two spots that is called for in the BGB. 

 One of the many new things I learned about gaskets last year is over torquing which is what most people do out of habit leads to leaks or future leaks because it will deform the elasticity of the rubber. Not everything needs to be tight. 

 This is why some have better results than others and its not luck.   

@dev I'm referring to the plastic "bolts" that hold the dust cover on top of the valve cover....

@pwnzor

Those are just push pins and not really bolts.

If you are good with a tap you can make your own threads and use any bolt you like in place of the plastic rivets. 

Back when I had my 1ZZ and broke off the rivets I just found a small enough bolt that griped the hole and I threaded it in, it held.  

@neomr2 Wow, that's great info!  Two of mine are broken off in the holes, so I'll gently drill them out, thread the holes and find some pretty red anodized bolts to stick in there... or something with shiny red on it.

Thanks!

I think these are the OEM valve cover bolts:

90105-06283

Pretty sure the spark plug boots are bolted with the same size.

If I remember torque specs are 7 ft-lb. I need to find a very tiny torque wrench for something that small. Usually recommended to torque in three phases. It's crazy how light of a torque spec this is.

For a job like this an electronic torque wrench works well. Mine goes from 5ftlb-100ftlb. 
I also did mine in a cross pattern in three phases.  
It will seem like it’s not enough but it is and will not leak.

That works out to 84 inch lbs which is a lot of torque for a small bolt, suggest using an inch lb torque wrench. 20 to 100 inch lb torque wrench is fairly common
