| | 4/20/05 The valves were shimmed on one side only. Worn springs? | |
| | | 4/20/05 Sloppy guide work galled the valves. | |
| | | 4/20/05 Double check these rings. Some are thinner than others. Should be 2.2mm. | |
|
| | | 4/20/05 Head failed because of crappy valve job. | |
| | | 4/20/05 No chance of sealing on #2. I heard these problem in the first leakdown. | |
|
| | 4/20/05 #3 exhaust lost it's seal also. | |
| | | 4/20/05 Prussian blue reveals non-concentric valve seat. | |
| | | 4/20/05 One angle. Notice the flash also hilites the roughness of the grinder. | |
|
| | 4/20/05 Sent the head to Headflow Masters for repair. | |
| | | 4/20/05 Heads arrived nice and safe. | |
| | | 4/20/05 New stainless steel exhaust valves. | |
|
| | 4/20/05 New studs. HFM didn't get the alignment right. Make sure they do. | |
| | | 4/20/05 Looks good but how does it measure up? | |
| | | 4/20/05 I love this tool. | |
|
| | 4/20/05 No shims: as it should be with new springs. | |
| | | 4/20/05 #1 valve seats. All new guides. | |
| | | 4/20/05 #1 with Prussian blue. | |
|
| | 4/20/05 #1 Intake looks good perhaps a little thin on the contact face. | |
| | | 4/20/05 #1 Exhaust looks good. | |
| |
| | 4/20/05 #2 with Prussian blue. | |
| | | 4/20/05 #1 intake looks good, perhaps a little thin on the conact face. | |
| | | 4/20/05 #2 Exhaust looks good. | |
|
| | | 4/20/05 #3 Intake looks good. | |
| | | 4/20/05 #3 Exhaust looks good. | |
|
| | | 4/20/05 #4 Intake looks good. | |
| |
| | 4/20/05 #4 Exhaust looks good. | |
| | | 4/20/05 Seats have correct hardness. | |
| | | 4/20/05 Clover lapping compound. | |
|
| | 4/20/05 Spread some 280 grit on the contact face of the valve... | |
| | | 4/20/05 Then use a lapping tool until you get a nice even grey band. | |
| | | 4/20/05 Intake contact should be near edge, exhaust near middle. Doh! | |
|
| | 4/20/05 Good leakdown results. Ready to run. | |
| | | 4/21/05 Block hole left by a/c compressor install. | |
| |
| | 4/21/05 Cover up hole left by missing TDC Marker. | |
