Services Performed
- Lots of faults stored but almost all where voltage related. Cleared faults and ran engine up to op temp to monitor running data. When engine warmed up camshaft phase position is ready 4.11 (service limit is 3-6*). Recommend timing chains replaced soon. Lots of vac at oil cap when running but no faults to suggest PCV issues, PCV is original and should be replaced when timing chains get done. Ignition coils are original. Spark plugs look in good shape, gap is .034 – recommend replace with timing chains and ignition coils just due to age. Cam girdle is leaking but oil does not show around lower timing cover very badly – car has barely been driven since last visit so not enough drive time to track down oil leaks. Battery very low on arrival but car has not been driven. Put on charger to charge to full and will perform battery test once charged.
- Replaced the timing chains, tensioners, guides, both upper and lower timing covers, cam bridge, all necessary hardware/parts. Torqued all to spec and followed factory procedures for repair. Test drove afterwards and had no issues.
- Re-sealed the cam girdle and replaced all proper hardware, also torqued to spec. Used factory procedures as well for re-seal, along with factory sealant. No leaks.
- Replaced the PCV valve, torqued to spec. Confirmed to leaks after installation.
- Replaced the spark plugs and ignition coils, torqued to spec. Confirmed no misfires afterward.
- Charged battery to full and performed test, tested at 50% capacity after charge. Recommend replace battery. Replaced battery during re-assembly, performed battery coding and verified no faults after test drive after battery replacement. Engine no longer lugs on startup.
