 After hot tanking I noticed different lengths on my exhaust valve guides. Between the four exhaust guides ( two heads) the length of the top of the guide out of the head varied by 2 mm. Is this a problem or just sloppy work from P.O. ? Does it matter ? |

QUOTE(pgollender @ May 19 2017, 07:30 AM)  After hot tanking I noticed different lengths on my exhaust valve guides. Between the four exhaust guides ( two heads) the length of the top of the guide out of the head varied by 2 mm. Is this a problem or just sloppy work from P.O. ? Does it matter ? The factoryguides didn't have shoulders. They'd slip down. Saw that a million times. It never hurt anything when they didn't slip down more than in the picture. Sometimes after slipping they would loosen further and start moving up and down in the guide bore. That would cause problems. I can't tell if the exhaust guides are O.E., but they didn't have a shoulder either. They weren't as prone to slip as the intakes. The intake guide bores on the 1.7 are really short. The exhaust are pretty long, so the guides weren't as prone to slip. |
