i didn't do the exhaust mods, i however have unrestricted the airbox and it has a K&N panel filter in it. The number was given to me in rough from a mechanic i have no idea what its running really. I know alot of engine work was done by the previous owner inlcuding replacing the injectors, throttle body and the belts so if i was to replace tappets i would most likely get it done by using the tool. At the moment i think theyre just noisy and i doubt theyre causing too much damage to the engine so i'm not too worried.

Hmm methinks someone's blagged a little bit to you

any easy way to unblock this?

As repairs go it’s not too difficult, sump off, unbolt the pick up tube, unblock it (soak it in petrol and clean out the mesh) or fit a new pick up. Put it back together with a new gasket, oil filter and fresh oil.
If the above sounds like double Dutch to you, then take it to a garage. It’s easy enough if you’re handy with tools but it needs doing right and would take a couple of hours max for a mechanic to do in a workshop.

The only way the pick-up gets blocked is through inadequate servicing in the past - sludge from oil that's not been changed on time.

Agreed, not helped by Vauxhall specifying 20k miles as the interval on an old engine design...

The previous owner didn't mention anything about serivces and by the state of the oil filter, i doubt it was changed at all the whole they owned it.

Seen the middle muffler delete and by the looks of it a previous owner has replaced quite a lot of the engine. Might take the heat shield off next time i get the chance and see of it look like a normal one. I do know the heat shield has been off recently as it has had new bolts.

This engine Hates pod/cone filters

MK2 Astra used to be like that as well. I bought one off a guy I worked with and he followed me to work one day. When we got there he asked what I had done as it had never gone so fast with him. I replied that I took off the cone filter he'd fitted and put back the original air filter box and a normal filter.

I don't think the OP realises that this engine is incapable of being 130Bhp with what he has said or been told.

I know its very possible its not making 130hp i never said it wasn't i only stated what i was told and that i believe all the mods i was told about are most likely there. Appreciate your input though.
