Re: New here, just bought '90 ZR-1
You have metal floating around in this motor,are you going to completely go through this thing or do a mild patch up and go from there?

 ), drivers head off, timing chains/cams and related assemblies off. Gonna take passenger head off and drop the oil pan. Inspect and clean everything real good esp in combustion chamber. Replace all gaskets of stuff I removed. Replace the bad valves, remove and inspect the others on that head. So yeah, probably just a mild patch up for now. But I am going to inspect everything as good as possible to find all the metal pieces. In the future when I have more money, I plan to freshen the engine up, prob get top end P&P and powdercoated, maybe get bigger pistons/sleeves, freshen bottom end, etc. Cams look a little bit worn at the tip on some of the lobes but look ok overall. I don't have the money right now to replace 4 cams. I just want to get it in running condition for as little money as possible for right now.

Re: New here, just bought '90 ZR-1
A couple of observations about this photo:
 1. What is that red chip from, that is laying in the cam cover? 2. You do know that the wear strip is missing, only the metal backing is still bolted (2 bolts) inside the cam cover. It was probably knocked off when the chain let go. 3.There is what appears to be a crack in the cam cover, on the left side of the picture, right below the wear strip backing plate. Can you verify? Knowing you are on a tight budget, I can't stress too much to make sure you use a GOOD welder with TIG machine to repair the cam cover. Heat must be controlled so the mating surfaces do not warp. It shouldn't be a problem to do if you use an experienced, skilled welder. Screw it up & it'll cost you a replacement head/cam cover assy. Should you decide to pull the oil pump for any reason, be very careful regarding the oil pump/crankshaft seal. The pump side of the seal is carbon & very easy to damage, and expensive to replace. When you get ready to go back together, should you need any help regarding what gaskets & seals you need, email me & I'll work with you on a list. jerry@jerrysgaskets.com

Re: New here, just bought '90 ZR-1
In response to your questions, Jerry:
1. That 'red' chip (which is actually not red, it's gold), is a piece of the plastic wear strip you mentioned. I didn't notice it there until after I took the picture. 2. Yes, I know there is a wear strip missing. It was in lots of pieces when I took the cover off, probably damaged when the chain let go. At the whiteracing website, he wants $120 for a piece of plastic. No way in hell am I paying that. It is listed on the GM parts website in their 'alternate catalog' for only $3.76, but it probably is not available anymore. I was planning on making one from the wear strips on the secondary timing chain guides I took out (I have a whole other set to go in) since it's the same type of plastic, maybe glue it on or something. I'm pretty good at 'macgyvering' things. 3. The crack your seeing is actually not below the wearstrip. It's part the damage seen in this picture in the center, top sort of:  I was planning on just using JB weld to do a temp repair on the cover for now. All it needs to do is keep the oil in, JB weld can withstand heat up to 600 degrees. In the future, I'll get it repaired properly. As for the gaskets, yes I was planning on getting the ones I need from your site, Jerry. I have all the ones I need so far in my cart (I created an account), may add a few if I remove more stuff. Any chance I could get a discount? It's gonna be pricey for all the gaskets I need.

Re: New here, just bought '90 ZR-1
To get the cam cover fixed I would go over to your local motorcycle shop. My Ninja broke it's chain and it damaged the aluminum case very similar to the damage you have on the cam cover. They had a good welder that tig welded it for me for $40 and the job was perfect and I didn't have to buy a new case.

Re: New here, just bought '90 ZR-1
Within the ellipse appears to me to be a hairline crack. is it an optical illusion?
