No, it wasn't AC Delco, I buy only avalivable: CLOYES.

I buy it From Rockauto. For my lucky i make rection when I hear first noise. Proably that why nothing else was happend.

Hi everyone! After 6k mil hard knocking noise forced me to disasemby timing case and camshaft case. It turned out that timing chain tensioner not hold the chain. I buy new timing set before and that new was broken. So that is worning for everyone do not trust new parts. I report that there is no licking oil under the head. Engine working fine, except one worning "camshaft sensor bank 1" code p340 and 341. That code become 3kmil ago. I buy new sensor but nothing change. Is it possible that engine computer is bad?

I have seen timeserts as way to fix damaged Bolt holes, but fixing engine was my first time that why I can believe everyone in everything. With all respect for Jan.

It looks good, I can even say very nice. On the threads was only rest of sealant. I change them becouse mechanik i asked too said that bolts should be new. Reason is that bolts become a bit longer during the time work engine. I will report when I see something wrong.

Only hope left over...

Thanks Jan! I disappoint you, because I used only new bolts for head. I even don't known that it's important to use Time Serts for it. If You say so, then I got hope that it will be enough and new head gaskets will not leak in future. Any way, thread on head screw looks different than usual thread. As I understand there exist kit for it?

Its not a problem with "check engine", that problem was solved already. There is no new codes, engine work proper Now I got other problem with radio/navi does't work totally. I dont know why, becouse I bought car with that fault. I check fuses and its ok. When I put power on (acu agin) cd changer positioning and thats all... Display is black. Another problem that turn signal blik rapidly, but bulb on front wok properly (bliks ) Is it right topic for it? maybe I should make new for SRX?

Thank you all for your help and support. Now is the time to play with by rear lamp and navigation. Can any of you feel strong enough to help me by electric components??

Hi! It take a while, but at least engine work (hope that for long years ) After disassembly heads it turned out that only 4 exhaust valves and 2 intake was bent. So, I did like I said before, drill new hols in place of old one, make new thread M8. // I think, if I was first, that means, that orginal M6 is strongly enough. That why M8.// Head was totally repaired, valves, gaskets, lifters, etc... Mount new timming set and idler sprocket. And engine WORKS!!! Already about 5 hours. IM PROUD FROM MY, becouse I did It by my self.

Hello! I apologize for my long silence, but I Got very havy week of wór. Im not a mecanik, so my car is ony hobby. My plan is to do like Logan says, but not M10 fix, Iwan to make M8 hole with new bolts. BodybyFisher, after my Holiday I make photos you want. Third Bolt head looks like new opposit to rest two. Logan, unfortunately, I am stil in Poland , and its very difficult to buy a used same motor...

Under is 3 photos, one hole isn't smashed, so I think that one bolt was broken as a new or when previous owner changing timming chain. Aparted bolt I found seamlessly keyed. Head of that bolt havent any scratch, rest bolts have. Thousands km and whidout one, rest making loose, til fell out totaly. I heard noises but it sound like valve lifters (in fact few shuld be changed), so I ride confident that I still have taime to change lifters.

Hi! Today I make a lot of detailed photos.

Unfortunately, the failure happend during ride when engine running.

Under is pictures I got before I take this to pieces.

Yes, behind that Sprocket are 3 bolts, correct was. For few howers I sed Pictures. I havent photos on mobile.

Thanks for fast answer, Im afraid that valves could hit the pistons. IS IT passible in this engine?

Hi I got cadillac SRX with LH2 4,6 engine, and chain is not broken but, screws from timing idler sprocket fall of and chain fsll out too. As i see I'm te first :(((((. Next post I send pictures. I wonder what now, what shud I fix more than timming?? Kris form Poland Sorry form my English mistakes.
