It sounds like he saw something he didn’t like, but what exactly was the problem? Is your car pulling timing or do the logs not look strong? What kind of ‘damage’ was done with your old header due to an exhaust leak?
@ cjd makes a great suggestion to make sure all of your exhaust bolts are tightened properly - both he and I had our header bolts loosen on the flange between the header and the secondary collector/overpipe, so you should check yours, too. I can imagine a scenario where loose header bolts could cause erroneous readings by the O2 sensor, which may affect the ECU and and your data logs. |
Rjk, did your headers make any rattling noise when the bolts were loose in on the flange and over pipe ? How did you know they were lose ?
