AngrySailor Posted October 5 Author Posted October 5 Cleaned only with a rag and solvent. Damage seems localized to the hot end which would be where clearance would disappear first. Can’t really feel that with my fingernail and the guides don’t look too bad either. Some light axial scratches at the bottoms. Might be ok with a hone for a little more clearance. 3 1 Quote

Got one head apart really looks like there just wasn’t enough clearance for the application/heat involved. It’s not like it warms up gently… going to talk to Brodix tomorrow and see what they think. Caught it real early, might be able to polish the valve stems and hone the guides, they’re not torn up bad at all but would have snow balled real fast. I’m going to leave the exhaust valve seals off at reassembly also. Should have done that first go around but I think they were still too tight clearance It will be interesting to hear what Brodix has to say. Hopefully the stems polish up and guides clean up with a hone job Is that VR1 synthetic? 1 Quote

Brodix said needs more clearance (obviously) and also seems to think that valve is scrap due to heat which doesn’t really make sense as it only ran no load, yeah it’s rich at idle but that blue tells me 550-600f which is nothing. These are inconel valves are rated for 1600f, WT-Heck they think is gonna happen under load and boost??? That valve is gonna be cherry red… Guide clearance measures about 0.0016-0.0018” with my little telescopic gage and a micrometer but I am going to have them checked at a shop and honed to 0.0023-0.0025” also no exhaust stem oil seals will be installed the oil is conventional non synthetic. I would probably break a motor in for ring seat with conventional oil always but I am considering the driven GP-1 semi-synthetic or AMSOIL has good products also. I don’t think I’ve had issues due to the VR1 but there’s probably better technology available now. Quote

Rich idle mixture should lower EGT The larger clearance will be better for sure when you get it to full load What material are the guides? Yes you got break in with conventional oil to seat the rings What type rings you got in it? Red Line has 20W-60 for drag motors Quote

Red Line has 20W-60 for drag motors It’s REALLY rich and throwing flames from the front 4 cylinders but I agree it can’t make 1600f at idle lol! bronze guides, total seal rings, leak down while diagnosing was only 5-7% across the board ill check out red line, I’ve got an oil to water cooler so 60 might be a bit thick depending on where my oil temp settles under load 1 Quote

560Dennis Posted October 6 Posted October 6 I’m just trying to make sure I understand what I’m seeing . I this from highest temperature full open valve ? Quote

Same valve Dennis, wider angle picture. Your bottom arrows are where the guide ends so she’s scuffed a little about 1/4” up into the guide. 15 hours ago, Rawleigh99 said: Brodix wants to sell you another set of valves!🤣 yeah I had a couple shops look at it including the place I got the block from and they all seem to think it’s not overheated. No valve heads have dry white or even much tan carbon on them. Pic is the other head, cylinder 8 on the left, 2 on the right, and also number 2 exhaust valve which was the hottest of those four. 4 Quote
AngrySailor Posted October 7 Author Posted October 7 7,5,3,1 ^ 8,6,4,2^ stems polished up with 2500 grit paper. Heads going for guide honing, give em a little more clearance and running no oil seals on the exhaust. hoping these rims are actually 5x4 1/2”. Seems like by the pictures they’re some goofy 5x4 1/4” pattern… didn’t even know that was a thing back then. Guess it’s 108mm??? 3 Quote
