machining mistake
So I was reading up some build threads today and saw that when the block was being machined it has to have the timing belt cover on it because the head actually rests on it. I didn't have this done and now I feel like an idiot.... I think so lol. What can or should I do now. The block had 0.013" taken off so there is a 0.013" difference between the block and the timing belt cover. I need to know what I should do
Thank you

Unfortunately the gasket and head overlap the top of the timing belt cover, so the block and cover need to be at the same level. What you read is correct, the safest way is to bolt the cover back on and have it machined down to the same height as the block.
PS; Have you put the block back into the Supra ? Last edited by Bill UK; 08-23-2010 at 08:29 PM. |

The upper cover isn't a huge concern, there's enough slack in the screw holes to account for taking a full millimeter off the head. The lower cover is the deal breaker.

 I don't know whether to laugh or ban you..... well, I guess I already answered my question. Seriously though. Blindly attacking it with a file or angle grinder is a HORRIBLE idea.... a belt sander would at least assure you of a more even surface. I'd attack it with a lapping plate with a piece of 320 sandpaper laminated to it and then some diamond lapping compound of decreasing grits to take it down (In fact I've had to do so in the past).

It has been a while since I changed my head gasket (about 10 years ago at around 142,000 miles) but I don't recall any issues with the timing cover. However, I did not take anything off the block.
But I did shave a little off of the head! Does that surface seal combustion, coolant or oil? If so, than proceed with care. Otherwise this should work!

That aperture between the block and the rear cam cover leads to a drain hole into the sump, as you will see if you put the gasket on top of the block there are two oil gallery’s that line up at the front. As you are only removing .013 thou and the cam cover is only cast ally, I would do as cre suggested.
